MARSI- ")EA is a beginner-friendly Expert Advisor (EA) that combines the logic of the Relative Strength Index (RSI) and a Simple Moving Average (SMA) to identify and execute trading signals on financial markets like XAUUSD (Gold).

The EA is built to demonstrate:

  • Dynamic lot sizing based on account risk

  • RSI-based overbought/oversold entry conditions

  • Trend filtering using a Moving Average

  • SL and TP levels adjusted to symbol tick precision

This EA is especially useful for learners who are experimenting with technical strategies and want to understand how indicator handles, dynamic risk, and broker digit differences affect trading logic.

Trading Logic

The EA operates with the following entry rules:

  • Buy when:

    • The current price is above the moving average (bullish)

    • RSI is below the oversold threshold (suggesting price will rise)

  • Sell when:

    • Price is below the moving average (bearish)

    • RSI is above the overbought threshold (suggesting price will fall)

  • Stop Loss and Take Profit are configured using _Point , adjusted based on the broker’s pricing precision ( _Digits ).
