Custom MACD Divergence EA

Hello developers,

I would like an EA based on EMAs, MACD divergence with price and interaction with MACD lines. Preferably in MT4.
Since divergence can be tricky it would be for the best if someone experienced did it.

MACD divergence is thought of this way: every time MACD histogram changes color (on candle close), look back at history corresponding with the previous color and identify low/high of price and low/high of MACD line and make values out of them. Then compare green zones together and red zones together. If two continous green zones have higher low - lower low, while having lower low - higher low on MACD line, we have a divergence (in this case the "hidden one"). Compare only last 3 green zones and 3 red zones at once. In this strategy, I use only hidden divergences (watching lows on uptrend and highs on downtrend) and only in one direction at a time. Theoretically, two of them could happen at the same time - divergence between 1st and 3rd, and 2nd and 3rd zones. In this case, go for the last one (2nd to 3rd zone).

Also MACD histogram value 0.000000 means no reversion (counts towards the current color).

Components: 150 EMA, 600 EMA (simulating higher TFs), MACD with MACD line (= histogram and two lines,  not one) (i have one in mq4 format if needed), 5 min chart.


Rules:

Long - 150 EMA higher than 600 EMA; hidden divergence between price and MACD line (= higher low - lower low on price while lower low - higher low on MACD line); MACD histogram changed color in between the MACD lows (red-green-red); between lows on MACD line - both MACD line and signal line are below the zero line, no touch of them with 0 line; if all above is satisfied, open a buy position (market order) next time MACD histogram closes in green.

Sell - vice versa (stil hidden divergence).

Only one active trade on a pair. SL 2 pips below last high/low (of price), PT 2 times the risk. Spread filter. Friday stop (enable-disable). Position size (manual/auto).

Inputs: Ema periods, MACD settings, SL buffer (2 pips), PT ratio (2 times), max spread (1 pip), Friday stop (true/false with XX.YY broker time, closes all positions no matter the outcome), position size  - manual = value in account currency/auto = percentage of balance.

When it is done, I would like you to do a backtest with quality data for at least 1 month (more = better), just to check and match the results (I trade this manually).

Good luck :).
