COASYN Directional Order Blocks MT5 – Adjustable Swing Reversal Filter

Project: COASYN Directional Order Blocks MT5 – Adjustable Swing Reversal Filter

I would like to modify my existing COASYN Directional Order Blocks indicator for MetaTrader 5, as already discussed and agreed with BRAINGRAIN TECHNOLOGIES LLP.

Requirements:

1. Add an optional, fully adjustable signal-to-opposite-signal minimum distance filter, measured in broker points.

2. When a SELL order block is confirmed, record the closing price of its confirmation candle as the reference. Track the lowest lows reached afterwards. Only allow a BUY order block once the specified downward distance has been reached and the normal COASYN BUY conditions are confirmed.

3. Apply the same logic in reverse for BUY to SELL, tracking the highest highs.

4. Keep the first confirmed SELL or BUY as the reference until a qualifying opposite-direction block is confirmed. Additional same-direction blocks must still be drawn and alerted, but must not reset the reference or accumulated distance.

5. Reaching the distance must never generate a signal automatically.

6. Preserve Structure Swing Length at 1 and the original COASYN order-block detection logic.

7. Include the optional ATR-based or fixed-points displacement mode, with adjustable minimum displacement points. Preserve the existing body percentage filter.

8. Preserve confirmed-candle alerts, popup/sound/push options and the existing EA-readable buffer indexes and values.

9. Use closed candles only, process historical candles chronologically without future data, and never generate historical alerts on startup.

10. With the new filters disabled, the indicator must produce exactly the same zones as the original version.

Deliverables:

• Full editable MQ5 source code and compiled EX5 indicator.

• A demo build for verification.

• A comparison report confirming identical original zones when filters are disabled.

• A short XAUUSD and EURUSD comparison showing the effect of different swing-distance settings.

The settings must be adjustable for different symbols and broker point sizes.

Agreed budget: $40 USD.

This project is intended for the same developer, BRAINGRAIN TECHNOLOGIES LLP, who completed the original COASYN indicator.
