Expert Advisor (EA) Operation & Update Report
This report outlines the operational logic of the strategy in MQL5 and explains the technical improvements implemented to resolve validation errors.
1. Operational Logic
-
Core Algorithm (EMA Ribbon): The primary engine driving the buy/sell decisions of this strategy is the sequence alignment of 15 slow Exponential Moving Averages (EMAs) ranging from period 24 to 66. This sequence logic, including the early/normal signal transition parameters, has been replicated in MQL5.
2. Resolution of Validation Errors
To resolve the errors encountered during the MetaTrader 5 market validation process, the following algorithmic fixes were integrated:
-
Invalid Volume Error: The EA now dynamically queries the broker's specific rules for minimum lot size, maximum lot size, and volume step size (SYMBOL_VOLUME_STEP) for the traded asset. The lot size input is automatically adjusted and normalized to conform to these rules.
-
No Money Error: The validation system often tests EAs with extreme parameters, such as a starting balance of $1.00. To prevent the EA from sending orders that exceed account limits, the OrderCalcMargin function was incorporated. The required margin is calculated prior to any transaction; if the account lacks sufficient free margin, the order request is bypassed without being sent to the broker.
-
Data Synchronization Check: To avoid errors caused by uninitialized indicator buffers when the EA is first loaded on a chart, the IsIndicatorDataReady check was introduced. This ensures that the EA waits for the terminal to calculate
