Piano
Piano is an MQ5 Expert Advisor whose source code is not available for review as the file appears to be in compiled binary format rather than readable MQL5 source code. Without access to the actual source code, a detailed analysis of its trading logic, entry and exit conditions, and risk management features cannot be performed reliably. The EA name 'Piano' does not clearly indicate a specific trading strategy or methodology.

Why this EA never traded: no entry rule survived the conversion.
Converted from MQL5 to Python and run with the same rules for every EA. Positions use MT5 lot sizes (100,000 units per FX lot, 100 oz per gold lot) with 1:100 leverage, one order at a time, and a stop-out below 10% of the starting balance. Sharpe is computed from the equity curve. Results marked as unreliable are shown for completeness only.
Blow-up risk: No blow-up pattern found
- Has no stop loss or trailing stop
On its own this is not a typical blow-up pattern, and the account was not stopped out in our backtests. That is not a guarantee: any EA can lose money.
High: stopped out in our backtest, or martingale/grid sizing without a stop loss. Elevated: martingale or grid sizing with a stop loss, or several positions at once without a stop loss. What the label means and what we found →
Strategy analysis
The source code file for this EA is in compiled binary format, making it impossible to read the actual code and accurately analyze its strategy concept, entry conditions, exit conditions, position sizing, and money management. The EA name 'Piano' might suggest a keyboard-style multi-level trading system, similar to a piano's scale structure, possibly employing multi-tier or multi-dimensional trading approaches. However, this is purely speculative based on the name alone with no code evidence to support it. Without access to the source code, any strategy analysis is entirely conjectural and should not be used as a basis for trading decisions. It is strongly recommended to obtain the source code version before conducting a detailed analysis. The EA may be part of the MQL5 CodeBase shared repository, and the source code could potentially be retrieved from the MetaQuotes official codebase.
Strengths
- The EA exists in the MQL5 CodeBase, suggesting it may be a community-validated project
- If the name implies a multi-tier structure, it could have a flexible trading framework
- As part of a published codebase, it may have some user feedback and testing history
Weaknesses
- Source code is unavailable, making it impossible to verify the safety and correctness of trading logic
- Risk management mechanisms cannot be evaluated, potentially leaving unknown risk vulnerabilities
- Lack of transparency prevents users from adjusting the strategy or fixing potential issues based on code
Possible improvements
- Provide a readable source code version (.mq5) for community review and improvement
- Add detailed strategy documentation including entry/exit rules and risk parameters
Risk assessment
Overall risk: High risk
- Source code is unreadable, unable to verify if high-risk strategies like Martingale or Grid are employed
- Cannot confirm whether stop-loss and position check mechanisms are in place, posing potential account blow-up risk
