Overview
Bober Lannister EA is a fully automated night scalping robot available for both MetaTrader 4 and MetaTrader 5. The core idea behind the system is focused and specific: it is designed to trade during night market conditions, but not in the extremely narrow way that many night scalpers do. Rather than concentrating all activity into a very short rollover window, Bober Lannister EA is described as operating across a wider night-time range of around three to six hours per day.

That distinction matters because it shapes the whole character of the EA. A night scalper that trades only around the most compressed and illiquid period of the day may be highly exposed to spreads, swaps, rollover pricing distortions, and broker-specific execution differences. Bober Lannister EA appears to take a broader approach, aiming to find opportunities throughout a larger low-volatility session instead of relying on one brief window. This makes the strategy more flexible in theory, although it still remains heavily dependent on spread quality, commission, execution speed, and suitable pair selection.
The MT4 and MT5 versions share the same general trading concept, recommended instruments, risk-control structure, and non-martingale profile. The MT5 version includes extra convenience modes, such as Portfolio mode, GBPUSD Beast mode, and Custom Setup mode, giving it a slightly more structured configuration framework than the MT4 version.

Trading Style and Market Logic
Bober Lannister EA is best understood as a night scalping system. It is not presented as a trend-following robot, grid recovery system, breakout strategy, or news trader. Its operating environment is the quieter portion of the trading day, when many currency pairs tend to move within more restrained ranges. This kind of strategy typically depends on identifying short-term inefficiencies, mean-reversion opportunities, or temporary price movements that can be captured before the market becomes more active again.
The EA’s stated advantage is that it trades over a relatively wide night-time window of three to six hours per day. This is one of the most important design details of the system. A wider trading window may allow the robot to avoid forcing entries during the single most sensitive rollover hour, when spreads can widen sharply and liquidity can become unstable. It may also allow the algorithm to be more selective, because it has more time to wait for suitable conditions.
However, the broader night window does not remove the typical sensitivities of a night scalper. Bober Lannister EA still appears to rely on low transaction costs and stable execution. Even if it is designed to avoid the worst rollover conditions, night trading often occurs when liquidity is thinner than during major sessions. This means that spread, slippage, commission, and broker quote quality can have a meaningful effect on results. The MT5 version specifically notes that lower spread and lower commission are preferable, which is consistent with the requirements of a scalping-style system.
Supported Platforms: MT4 and MT5
The existence of both MT4 and MT5 versions is useful because traders can choose the version that aligns with their broker environment and preferred platform. The MT4 version is named Bober Lannister, while the MT5 version is explicitly named Bober Lannister MT5. In practical terms, both are intended to provide the same broad concept: automated night scalping on selected forex pairs.
The MT5 version appears more developed in terms of built-in operating modes. Its Mode setting includes Portfolio, GBPUSD Beast, and Custom Setup. Portfolio mode is designed as a one-click arrangement for running multiple pairs with pre-adjusted currencies and inputs. GBPUSD Beast mode narrows the focus to GBPUSD with adjusted inputs for that specific setup. Custom Setup mode is intended for users who want the EA to work according to the settings configured in the input tab, including when applying live sets.
The MT4 version has a more straightforward settings list. It includes order type, magic number, lot selection, lot percentage, fixed lot, range, time filter, start and end time controls, maximum drawdown protection, waiting hours after drawdown protection is triggered, and a Friday trading toggle. This makes the MT4 version simpler, while the MT5 version adds more structured presets.
Recommended Pairs
Bober Lannister EA is not described as being limited to a single currency pair. The recommended or favored pairs include EURCHF, GBPUSD, EURNZD, CHFJPY, and EURAUD, with the possibility of using other pairs through suitable sets. This basket gives the EA a multi-pair character, especially in the MT5 version where Portfolio mode is specifically designed to run several pairs at the same time.
The pair list is interesting because it includes both relatively lower-volatility combinations and more active cross pairs. EURCHF is often associated with tighter, more range-like movement, while GBPUSD and pairs such as EURNZD or EURAUD can move more aggressively. That means Bober Lannister EA is not simply restricted to the quietest instruments. Instead, it seems to rely on pair-specific settings to adapt the night scalping logic to different market behaviors.
This is important for risk control. A set that works on EURCHF cannot automatically be assumed to work the same way on GBPUSD or EURNZD. Cross pairs can have wider spreads, larger overnight fluctuations, and different liquidity patterns. The availability of live sets and custom configuration is therefore relevant to the EA’s practical use, because the robot’s performance may depend strongly on matching the settings to the instrument.
Order Execution Options
The EA includes an OrderType setting that allows the use of limit or market orders. This is an important design choice for a scalping robot. Market orders prioritize execution, while limit orders prioritize price. In low-liquidity night trading, that difference can be significant.
Market orders may enter more reliably, but they can also suffer from slippage when spreads widen or quotes move quickly. Limit orders may help control entry price, but they may not always be filled. For a night scalper, this trade-off is central. A strategy that captures small price movements needs careful entry quality, and the choice between limit and market execution can affect both frequency and average trade outcome.
The presence of this setting gives Bober Lannister EA some adaptability. Traders can potentially choose the execution style that works best with their broker’s conditions. If a broker has fast execution and stable spreads, market orders may be practical. If price precision is more important, limit orders may be preferred. The best choice is likely to depend on the pair, spread behavior, and server conditions.
Lot Management and Position Sizing
Bober Lannister EA supports both fixed and floating lot calculation. The Lot setting determines the type of lot calculation, while Lot Percent and Fixed Lot provide the relevant values. This gives the user two broad approaches to risk sizing.
Fixed lot trading keeps position size constant regardless of account balance changes. This can make performance easier to interpret because trade size does not automatically increase after gains or decrease after losses. Floating lot calculation, by contrast, allows exposure to scale according to a percentage-based value. That can be useful for proportional account management, but it can also amplify drawdown if the chosen percentage is too aggressive.
The minimum deposit is stated as 100 USD, but that does not necessarily mean every configuration is suitable for such a small account. Multi-pair trading, floating lot sizing, and more volatile instruments may require more margin and more room for drawdown. For a night scalping system, small accounts can be particularly sensitive to commission, spread, and minimum lot constraints. A conservative fixed-lot setup may therefore be more appropriate for testing and early use than aggressive percentage-based sizing.
Risk Controls
One of the most relevant settings in Bober Lannister EA is MaxDD. This function is described as closing all positions after reaching the MaxDD value to prevent further losses. This is a direct account-protection mechanism and is especially important for a scalping robot that may trade multiple pairs.
The MaxDD feature does not eliminate risk, but it does define a hard defensive action when losses reach a chosen threshold. This can prevent an open basket or series of trades from continuing beyond the user’s tolerance. However, the effectiveness of this feature depends on the chosen MaxDD level and actual execution conditions. In fast or illiquid markets, closing positions may still occur with slippage, and drawdown may exceed the intended level during sudden moves.
The Waithours setting works alongside MaxDD. After the maximum drawdown condition is reached, the EA can wait a specified number of hours before opening new trades. This is a useful cooling-off mechanism. Without it, a robot might close losing positions and then immediately re-enter during the same unfavorable market conditions. By forcing a pause, Bober Lannister EA can avoid repeatedly trading during a problematic session.
The Friday setting is another important risk-control option. Keeping Friday trading disabled can help avoid weekend exposure. For a night scalper, holding trades into the weekend can create gap risk, wider spreads, and unpredictable reopening conditions. The ability to disable Friday trading is therefore directly relevant to the EA’s operating style.
No Martingale Approach
A notable feature of Bober Lannister EA is that it is described as not using martingale or a dangerous strategy. This is an important point because many night scalpers and recovery-style robots rely on increasing position size after losses. Martingale methods can create smooth short-term equity curves until a large adverse move causes severe drawdown.
A non-martingale profile makes Bober Lannister EA more appealing from a risk-structure perspective. It suggests that the robot is not designed to recover losses by repeatedly increasing lot size. That does not make it risk-free, and it does not guarantee stable performance, but it does reduce one of the most dangerous structural risks found in many automated systems.
The risk profile still depends on lot sizing, pair selection, trading hours, broker costs, and drawdown settings. A non-martingale scalper can still lose money, especially if it is run on unsuitable pairs or with excessive risk. But avoiding martingale logic is a meaningful positive for traders who want a cleaner and more controlled approach to automated night trading.
Time Filter and Session Control
The TimeFilter, StartHour, Startminute, EndHour, and Endminute settings allow users to define the EA’s trading window. This is central to the system because Bober Lannister EA is built around night trading. The ability to control the exact start and end times makes it possible to adapt the robot to broker server time, pair behavior, and preferred trading conditions.
Session control is particularly important because different brokers use different server times. A night scalping window on one server may not align with the same market hours on another server. Without proper adjustment, the EA could trade outside the intended period. The inclusion of start and end time settings gives users the tools needed to align the strategy with the desired session.
The broader three-to-six-hour night range means the EA is not simply a rollover-hour tool. That may help it avoid some of the most extreme spread conditions. Still, users should be careful when setting the session, especially around daily rollover and periods where spreads are known to widen. The EA’s performance may be materially different depending on whether it trades before, during, or after those conditions.
MT5-Specific Modes
The MT5 version of Bober Lannister EA stands out because of its mode selection. Portfolio mode appears to be the most convenient option for multi-pair use. It allows users to run several pairs at the same time with currencies and inputs already adjusted. This is useful for traders who prefer a simplified setup and want to rely on preconfigured logic rather than manually adjusting each symbol.
GBPUSD Beast mode is a more specialized option. It is designed to run only GBPUSD with adjusted settings. This suggests that GBPUSD is treated as a distinct setup rather than just another pair in a broad basket. Since GBPUSD can be more volatile than some other night-scalping pairs, a dedicated mode may help tailor entries, risk, and timing to that instrument’s behavior.
Custom Setup mode is the most flexible. It uses the input tab settings and is the appropriate mode for applying specific live sets. This mode is likely best for users who want more control or who are testing different instruments and configurations.
Backtesting Considerations
The MT5 version includes a backtesting recommendation using MetaQuotes-Demo, modelling quality based on real ticks, and a testing period from 2017 onward. This is relevant because night scalping systems should be tested with high-quality tick data. Ordinary bar-based testing can be misleading for scalpers because spreads, entry price, and intrabar movements matter greatly.
Using real ticks is a more appropriate testing method for a strategy like Bober Lannister EA. Since the EA may depend on small price movements, the quality of historical tick modelling can influence the reliability of test results. Testing from 2017 onward gives a broad historical window that includes different market regimes, although any backtest must still be evaluated cautiously.
Backtesting should also be performed with realistic spread and commission assumptions. A night scalper can look much stronger under ideal costs than it does under real broker conditions. For Bober Lannister EA, testing should ideally compare different spreads, pairs, risk settings, and trading windows.
Broker and Leverage Suitability
The MT5 version states that the EA is not broker sensitive, while also noting that lower spread and commission are better. This combination should be interpreted carefully. It may mean the EA can run on different brokers, but its best results are still likely to come from brokers with favorable trading costs.
Recommended leverage options include 1:30, 1:100, and 1:500. This range indicates that the EA can be adapted to different regulatory and account environments. However, higher leverage should not be confused with lower risk. High leverage increases available margin, but risk is still determined by lot size, number of open positions, drawdown settings, and market movement.
For a multi-pair night scalper, margin availability matters because several trades may occur across different symbols. But the more important question is whether the account can absorb normal strategy drawdown without being forced into excessive exposure. A conservative setup with controlled lot sizing is more important than simply choosing high leverage.
Strengths
The main strength of Bober Lannister EA is its focused strategy design. It is not trying to be a universal robot for every market condition. It is clearly positioned as a night scalper with specific pair preferences, time controls, and risk settings.
Another strength is the stated avoidance of martingale. This makes the risk structure cleaner than systems that rely on recovery multipliers. The MaxDD and Waithours settings also add meaningful defensive controls, especially when multiple symbols are being traded.
The MT5 version’s Portfolio and GBPUSD Beast modes are practical advantages. They reduce setup complexity and allow the EA to be used either as a basket-style night scalper or as a focused GBPUSD system. The Custom Setup mode preserves flexibility for users who want to apply specific configurations.
Limitations
The biggest limitation of Bober Lannister EA is that its strategy type is naturally sensitive to trading conditions. Night scalping depends heavily on spreads, commissions, slippage, and liquidity. Even if the EA is designed to trade across a wider night range, it still operates during hours when pricing conditions can vary significantly between brokers.
Another limitation is that the EA’s effectiveness may depend on using suitable sets for each pair. The recommended pairs are diverse, and each instrument has different spread behavior and volatility. Poor configuration can weaken performance, especially on cross pairs with wider costs.
The minimum deposit of 100 USD is accessible, but it should not be treated as an ideal account size for every setup. Running multiple pairs or using floating lot sizing on a small account could increase risk quickly. Conservative sizing and controlled testing are important.
Final Verdict
Bober Lannister EA is a specialized automated night scalping system for MT4 and MT5. Its most distinctive feature is the wider night trading window of around three to six hours per day, which separates it from scalpers that concentrate almost entirely on the rollover hour. The EA supports multiple forex pairs, includes fixed and floating lot options, offers limit or market order execution, and provides drawdown-based protection through MaxDD and Waithours.
The MT5 version is the more feature-rich of the two because it includes Portfolio, GBPUSD Beast, and Custom Setup modes. These modes make it easier to run the EA either as a multi-pair system or as a dedicated GBPUSD setup. The MT4 version is simpler but still includes the core controls needed for order type, lot sizing, time filtering, drawdown management, and Friday trading restriction.
The strongest point of Bober Lannister EA is its combination of focused night scalping logic and non-martingale risk structure. The main caution is that night scalping is always sensitive to broker conditions, especially spreads, commissions, and execution quality. Traders considering the EA should pay close attention to pair selection, session timing, lot sizing, and drawdown parameters. Used conservatively and tested under realistic conditions, Bober Lannister EA presents itself as a focused and configurable night scalping robot rather than a broad, all-market trading system.
