Custom Logic For Trading Mini

Source-first execution framework for MetaTrader 4 and MetaTrader 5.

This package connects a custom indicator buffer to a small, readable order-execution layer. It is intentionally a framework, not a trading strategy and not a profitability claim.

Included

• Custom Logic For Trading Mini.mq4 — MT4 Expert Advisor source
• Custom Logic For Trading MT5 Mini.mq5 — MT5 Expert Advisor source

What it does

1. Reads a selected buffer from a custom indicator.
2. Interprets that value as a price cross, level cross, or non-empty symbol signal.
3. Enters on a false-to-true signal transition.
4. Supports long-only, short-only, or both sides.
5. Applies fixed lot size, optional stop loss/take profit, an order cap, opposite-signal closing, and optional break-even.

Quick start

1. Copy the matching .mq4 or .mq5 file to the terminal's MQL4/Experts or MQL5/Experts directory.
2. Compile it in MetaEditor.
3. Set indicator_name to the indicator path relative to the matching Indicators folder. Include a subfolder when needed, for example MyFolder\\MyIndicator.
4. Choose the correct buffer index and signal type.
5. Start with a demo account and verify the indicator's buffer meaning before enabling live execution.

Important behavior

• The original rolling-array signal flow is preserved: the first observed state after attachment is ignored, and a trade requires a later false-to-true transition.
• A persistent old buffer value remains true-to-true and cannot repeatedly re-arm an entry.
• An unavailable indicator value is not appended to signal history and never becomes a signal, including when ReversalLogic is selected.
• maximum_order = 0 means no framework-level cap. Positions are counted only when symbol and magic number match.
• take_profit, stop_loss, break_even_trigger, and break_even_target are distances in points, not pips.
• Indicator input parameters are not guessed or hard-coded. If the indicator requires non-default inputs, expose them in the EA and pass them to iCustom as part of your own integration.

Scope and safety
