The Arbitrage Thief Index (ATI) is a technical indicator used in the financial markets to detect potential price discrepancies and exploit them for profit. This indicator is designed to identify situations where an asset is overvalued or undervalued in comparison to its true value, which may result in a profitable arbitrage opportunity. In this article, we will explore the concept of the Arbitrage Thief Index and how it can be used by traders to identify and exploit arbitrage opportunities in the financial markets.
What is the Arbitrage Thief Index?
The Arbitrage Thief Index (ATI) is a technical indicator used in the foreign exchange (forex) market to identify potential arbitrage opportunities. It is based on the principle that when an arbitrage opportunity exists between two currency pairs, the cross-currency pair that involves the currency with the highest liquidity will reflect the imbalance first. The ATI is calculated by subtracting the bid price of a highly liquid currency pair from the asking price of a less liquid currency pair and then dividing by the spread of the less liquid currency pair. If the resulting value exceeds a certain threshold, it suggests that an arbitrage opportunity may exist. However, it is important to note that the ATI is not a foolproof method for identifying arbitrage opportunities and should be used in conjunction with other forms of analysis.
Arbitrage Thief Index Strategy
The “Arbitrage Thief Index” (ATI) trading strategy involves buying or selling three currency pairs based on specific conditions. For a buy signal, it is recommended to purchase all three currency pairs when the ATI falls below 35 Level, and the ATI R-SCORE is greater than 50.

To minimize losses, set a stop loss a few pips below the entry point or based on your money management strategy. When the ATI touches the 50 Level, it is time to close all trades.
For a sell signal, the strategy is to sell all three currency pairs when the ATI moves above the 65 Level, and the ATI R-SCORE is greater than 50. To minimize losses, set a stop loss a few pips above the entry candle or based on your money management strategy.

Again, when the ATI touches the 50 Level, it is time to close all trades. It is essential to note that this strategy is based on the default settings, and adjustments can be made to suit individual preferences. Additionally, it is crucial to manage risks properly, and traders should not invest more than they can afford to lose.
