Questions
What is HPMA102?
HPMA102 is a MetaTrader 4 Indicator source file. Static analysis documents Trend, 17 exposed input declarations, and 0 include dependencies.
Does this source include verified performance results?
No. This page is based on static source-code analysis and does not provide a backtest, live result, profit, win-rate, or drawdown claim.
What is required before compiling this file?
Place the source in the matching MetaTrader folder and compile it in an isolated MetaEditor data folder before use.
Why are some external URLs retained in the code?
Only detected functional runtime endpoints are retained to avoid breaking WebRequest or network behavior. Non-runtime URLs and contact details are replaced with the B123 site URL.
Do I need an account to download the source?
Yes. Registration and sign-in are required. WooCommerce grants the private download through a zero-total order, with an initial limit of 3 distinct free source products per site day.
Need a ready-to-use EA instead of source code?
This free download is useful when you want editable MT4 Indicator source code. If you want a cleaner ready-to-use path, compare it with the paid BBTrading products that already include private delivery, setup notes, and backtest evidence where available.
Paid BBTrading alternatives to compare
These products are selected by platform, detected code signals, and available catalog evidence. They are comparison options, not a claim that they use identical logic.
- Mon Scalper EA – Profitable backtest
- Sigma Trend Protocol EA V1.0 MT4 – Profitable backtest
- The Real Gains Algo EA V1.0 MT4 – Profitable backtest
Want this source checked or fixed?
Diagnostic status: compile_not_run. If the file does not compile, has missing dependencies, or behaves differently on your broker, use the page details when contacting B123/BBTrading support. The free source is a starting point; fixed, compiled, or backtested alternatives may save time.
Common reasons a free source may need work
- missing MQH include files or custom indicators
- legacy MQL syntax written for an older compiler
- broker-specific symbols, digits, spreads, or execution modes
- inputs that need risk review before any demo test
