The code provided is an MQL5 Expert Advisor (EA) script that is based on the idea of closing open positions when they have reached a user-defined profit or loss threshold, calculated as a percentage of the account balance.
The EA does not provide any entry signals or market timing rules; its main purpose is to manage the risk of existing positions by closing them when a certain profit or loss threshold is reached.
External variables used in the code:
-
RiskPercentage : This variable represents the maximum allowed loss per trade as a percentage of the account balance. When the current loss of an open position reaches this percentage, the position will be closed to limit the risk.
-
ProfitPercentage : This variable represents the desired profit per trade as a percentage of the account balance. When the current profit of an open position reaches this percentage, the position will be closed to secure the profit.
Since this EA is focused on risk management and does not rely on any specific market indicators, it can be applied to any symbol or timeframe. However, it is essential to note that this EA should be combined with a trading strategy that includes entry signals and other trade management rules to make it a complete trading system.
If you were to use this code as an include file (by placing it in the MQL5\Include folder), its main purpose would be for risk management by closing positions based on user-defined profit and loss thresholds.
You can combine this include file with other include files that serve specific purposes, such as calculating position size based on account risk, trailing stop-loss, and more. To do so, you can use the #include directive in your main EA file to include this file, and then call the CheckTrades() function when needed to manage the open positions.
