The EA operates using a grid trading approach combined with technical indicators. According to its official product page, it incorporates EMA (Exponential Moving Average) to filter market trends and CCI (Commodity Channel Index) to determine entry points.
It is important to note that the developer explicitly classifies this EA as high risk, warning that users may either achieve profit or lose everything.

Core Trading Logic
The trading logic of Gridder is clearly defined by two main components: indicator-based filtering and grid execution.
EMA Trend Filter
The EA uses the EMA indicator to filter the direction of the trend. This means that trading decisions are influenced by trend conditions identified through EMA settings.
CCI Entry Mechanism
For entering the market, the EA relies on the CCI indicator. This component determines when trades are opened within the broader trend context.
Grid-Based Execution
The EA is described as a grid Expert Advisor, meaning it places multiple orders in a structured manner rather than relying on a single trade. The grid logic is combined with indicator filtering to guide trade placement.
Manual Market Condition Filtering
A notable feature is the ability to manually filter flat and trending market conditions or specific traded symbols. This allows the user to decide when the EA should operate depending on market structure.
Lot Calculation And Position Management
One of the key aspects of Gridder is its approach to lot sizing and order placement.
Smart Lot Calculation
The EA calculates lot sizes using what is described as a smart algorithm. This calculation depends on the location of orders, meaning that position sizing is dynamically adjusted based on where trades are placed within the grid.
Balance-Based Adjustments
There is also an option to use a balance multiplier. This feature adjusts lot sizes according to the relationship between the current balance and the initial balance.
Lot Multiplier Option
In addition to the balance multiplier, the EA includes a separate lot multiplier parameter. This allows further modification of trade sizes within the system.
Recommended Lot Guidance
The developer provides a recommended lot size of 0.02 per 1,000 balance units. This serves as a guideline for configuring the EA.
Order Distance And Grid Control
A significant feature of the EA is its method for controlling the spacing between orders.
Minimum Distance Filter
The EA includes a filter that determines the minimum distance between unidirectional orders. This distance is calculated based on a percentage of the average daily candle over 21 days.
ATR-Based Distance Logic
The percentage parameter is tied to the average daily candle value over 21 days, allowing the EA to dynamically adjust spacing based on market conditions.
Deposit Protection Intent
This distance filtering is designed to prevent excessive load on the deposit by limiting how closely orders can be placed.
Profit Management System
The EA uses a structured approach to profit-taking.
Fixed Profit By Deposit Percentage
Profit is fixed based on a specified percentage of the account balance. This means trades are closed when a predefined profit level relative to the balance is reached.
Efficient Profit Capture
The system is described as being able to fix profit at minimal price rollback. This suggests that trades are closed quickly once profit conditions are met.
Increased Frequency Of Profit Closures
Because of the efficient lot calculation and distance filtering, the EA aims to increase the frequency of profit-taking events.
Drawdown Reduction Mechanism
The combination of indicators, distance filters, and profit logic is intended to reduce drawdowns.
Closing Methods
The EA provides multiple options for closing trades.
Unidirectional Profit Closing
Trades can be closed based on the profit of orders in the same direction.
Total Profit Closing
Another option allows closing based on the total profit of all open trades.
Combined Method
A combined closing method is also available, allowing both approaches to be used together.

Risk Disclosure
The EA includes a clear and direct risk statement. It is explicitly described as a high-risk grid EA, with the possibility of losing the entire account balance.
The developer strongly advises users to test and optimize the EA before purchasing or using it in live trading.
Version And Availability
The EA is available for purchase at a price of 50 USD and has a demo version available for download. It has recorded demo downloads and limited activations, indicating user engagement on the platform.
Conclusion
Gridder is a grid-based Expert Advisor that integrates EMA and CCI indicators to guide trading decisions while using structured order placement and dynamic lot calculation. Its design focuses on combining indicator filtering with grid execution, supported by configurable parameters for distance, profit targets, and lot sizing.
The EA emphasizes controlled order spacing using calculations based on average daily candle values and includes multiple closing methods to manage trades. However, it is clearly labeled as high risk, with explicit warnings about the potential for total loss.
Overall, Gridder provides a configurable framework for grid trading with defined logic and inputs, but requires careful testing and optimization as recommended by its developer.
