Strategy analysis
The source code file is in binary format and cannot be read, making detailed analysis of the strategy concept, entry conditions, exit conditions, position sizing, and money management impossible. Based on the filename 'Billy expert,' this is likely a personal strategy EA contributed by a community member named Billy. The specific indicators used, signal logic, and risk control mechanisms cannot be extracted from the binary file. It is recommended to obtain the MQ5 source code text version for a complete re-analysis. In the absence of source code, the risk assessment for this EA should remain cautious. Without verifiable logic, any trading with this EA carries unknown risk.
