I only accept only programmer whose rating is good and also did more than 50 jobs.
I need the source code and also the programmer should allow me to test the code for 2 more days and to make reasonable adjustment if there is any problem with the code.
I need someone to make modification to an existing MQL4 EA
Attached is the EA, this EA is solely use on Dow Jones Industrial Average, NASDAQ and SPX.

In this EA, the trailing stop is suppose to:
For buy trade, it will look at the highest high bar after the buy trade is initiated. Based on the high of the highest bar and minus off ATR(s) of the previous bar and come out with KTBTrailingStop. If the existing stoploss and the order entry price is below the KTBTrailingStop, then modify the existing stop to KTBTrailingStop. If the KTBTrailingStop is below the order entry price and the existing stop loss price, do not make any changes.
For sell trade, it will look at the lowest low bar after the sell trade is initiated. Based on the low of the lowest bar and plus ATR(s) of the previous bar and come out with KTSTrailingStop. If the existing stoploss and the order entry price is above the KTSTrailingStop, then modify the existing stop to KTSTrailingStop. If the KTSTrailingStop is above the order entry price and the existing stop loss price, do not make any changes.
For the trailing stop, I noticed the existing code did not trigger after the conditions are met. Please see if there are any changes need to be made.
The existing breakeven stop works perfectly but I am not sure if the int start() is correctly written. What I want is:
1. if the UseMoveToBreakeven=FALSE and the UseTrailingStop=TRUE, the EA should be able to use TrailingStop only and should not be using the BreakevenStop.
2. if the UseMoveToBreakeven=FALSE and the UseTrailingStop=FALSE, the EA should not be able to use TrailingStop and should not be using the BreakevenStop.
3. if the UseMoveToBreakeven=TRUE and the UseTrailingStop=FALSE, the EA should not be able to use TrailingStop only and should be using the BreakevenStop.
4. if the UseMoveToBreakeven=TRUE and the UseTrailingStop=TRUE, the EA should be able to use TrailingStop and the BreakevenStop.
So upon initiate a position, if the price moves to its favour and trigger the breakeven loss function, the stoploss will move toward the level determined by the breakeven function.
If the price did not move in favour and did not trigger the breakeven loss function, the stop loss should stay at the risk level.
After the price triggered the breakeven function, it will depend on the trailing stop function without changing the price target.
For the OrderSend part, I need the EA to do resend the order if there is any error. The resend of order should look something like:
for(int i=OrderTotal()-1; i >=0;i--) { if(OrderSelect(i,SELECT_BY_POS, MODE_TRADES)) { if(OrderType()==OP-BUY && OrderMagicNumber()==Magic Number) { while(true) { bool result = OrderClose(OrderTicket(),OrderLots(),Bid, 3, Red); if(result!= true) { int err = GetLastError(); Print("LastError = ",err); } else err = 0; switch(err) { case 135://ERR_PRICE_CHANGED case 136://ERR_OFF_QUOTES case 137://ERR_BROKER_BUSY case 138://ERR_REQUOTE case 146:sleep(1000);RefreshRates();i++;break;//ERR_TRADE_CONTEXT_BUSY } } } } }
Also need to create a function for the EA to add on more position when the existing position is making profit. This add more winning position function should only be activated when the price moves in favour of the position by 3 ATRs and when a new high is formed after a long position is initiated or a new low is formed after a short position is initiated.
There should be an input to key in the factor (1-10) and for the ATR that moves in the favour of the position as well.
Since this function is similar with the trailing stop function, it should come in before the trailing stop function. It should add on more position before the EA moves higher for the long trailing stop and before the EA moves lower for the short tailing stop.
The input should have a bool UseAddWinner=TRUE to activate this function and the function should start with AddWinner() just like the way I do it for AdjustTrail()
The example is below.
Long Position
Current long Position 5 contract and average cost is 24,600
Highest high after initiate long position 24,900
Offer price now is 24,871 and the bid price is 24,870.9
Stop loss price is 24,720
Factor = 3
Average price after buy more contract = ((Stop Loss Price – Average Price) * (1/Factor)) + Average Price
((24,720 - 24,600) * (1/3)) + 24,600 = 24,640
Calculation to buy number of contract = Current Long Position / ((Offer Price - Average price after buy more contract) / (Average price after buy more contract - Current Average Price))
5 / ((24,871 - 24,640) / (24,640 - 24,600))
= 0.866
Round down to the nearest 2 decimal place = 0.86
Short Position
Current short Position 3.5 contract and average cost is 24,700
Lowest low after initiate long position 24200
Offer price now is 24,351 and the bid price is 24,350.9
Stop loss price is 24,500
Factor = 3
Average price after short more contract = ((Stop Loss Price – Current Average Price) * (1/Factor)) + Current Average Price
((24,500 - 24,700) * (1/3)) + 24,700 = 24,633.33
Calculation to short number of contract = Current Short Position / ((Bid Price - Average price after short more contract)/(Average price after short more contract – Current Average Price))
3.5 / ((24,350.9 - 24,633.33) / (24,633.33 - 24,700))
= 0.826
Round down to the nearest 2 decimal place = 0.82
