Free MT4/MT5 Source: Custom Indicator Buffer to Trade Framework

WHY THIS FRAMEWORK EXISTS

A custom indicator can leave an old non-empty value in its buffer for several ticks or for the rest of a bar. If an EA treats every non-empty read as a new signal, the same old value may repeatedly trigger entries.

This framework preserves separate rolling long and short signal histories. The first observed state is ignored, and a trade is accepted only after a later valid transition from false to true. An unavailable buffer read is skipped rather than inserted as false, so a temporary read failure cannot re-arm a stale signal.

WHAT IS INCLUDED

- MT4 and MT5 source files

- Price-cross, level-cross, and symbol/arrow buffer modes

- Direct or reversed interpretation

- Long only, short only, or both directions

- Fixed lot size, optional stop loss and take profit

- Optional position limit, opposite-signal closing, and break-even

- Configurable indicator shift

- README, changelog, flow image, and MIT license

IMPORTANT

This is an execution framework, not a complete trading strategy. It requires a compatible custom indicator and uses that indicator default inputs unless you extend the iCustom call. Check the correct buffer indexes and signal meaning in Strategy Tester and on a demo account before live use. No profitability or win-rate claim is made.
