Done, Sir.

Here is my parameter for this EA. I hope someone with a good heart to help me finish this work:

li.li1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px 'Helvetica Neue'} ol.ol1 {list-style-type: decimal}
  1. Pair: EURUSD
  2. Timeframe: 30mins
  3. Using the MACD indicator
  4. Entry Order (Buy and Sell) execution at the open of the current candle based on these conditions:
    1. Set Buy Order after the first Rising Histogram (from previous falling histogram) 
    2. Set Sell Order after the first Falling Histogram (from previous rising histogram) 
  5. Execute Stop Loss parameter at the 5 pips lower (for buy order) from lowest price or 5 pips higher (for sell order) from highest price, 
  6. Execute Take Profit parameter based on 90% of previous candle (of the first rising histogram for buy order, and of the first falling histogram for sell order) body size (open and close price)
  7. Risk 2% of capital per trade
 

Hi Sir,

You need to change this to:

        request.price = ask; // Use ask price for Buy orders
        request.sl = ask - stopLossPips * _Point; // Set your stop loss
        request.tp = ask + stopLossPips * _Point * 2; // Set your take profit
        request.deviation = slippage);
