SUMMARY
I need an EA in MT5 that trades based on candle pattern on Daily timeframe. It must check and correctly process possible errors in trading operations.
Position is short only with entry at open of candle and pyramiding of positions. 

INPUTS

	AverageFast1 = 20	// fast simple moving average 1
	AverageSlow1 = 30	// slow simple moving average 1
	AverageFast2 = 20	// fast simple moving average 2
	AverageSlow2 = 21	// slow simple moving average 2
	RSIlevel = 50		// RSI level
	TrailingSL = 		// trailing Stop Loss at % of distance from lowest low (0 = not used)
	Ratio = 1.2		// Ratio exit
	Period = 20		// Period exit

MONEY MANAGEMENT	
Position size as per either fixed amount or fixed lot
	fixed amount = 10,000	// in fixed amount (e.g. if fixed amount is 10,000 and DE40 index trades at 15,000 then position should be 0.67 lots. If DE40 index trades at 9,000 then position should be 1.11 lots)
	fixed lot = 1.0		// in fixed lot

FILTERS ENTRY
	Condition1 = average(AverageFast1,close) < average(AverageSlow1,close);
	Condition2 = average(AverageFast2,close) < average(AverageSlow2,close);
	Condition3 = RSI > RSIlevel;
	Condition4 = entry1 > last trade bar

RULES TO OPEN LONG POSITION
Enter positions only at open of candle

If average(AverageFast1,close) CROSSES UNDER average(AverageSlow1,close) then barindex = entry1 // to mark the time of moving average crossover

If no opened position AND Condition1 AND Condition2 AND Condition3 AND Condition4 then
Sellshort position at market

RULES TO ADD ON EXISTING POSITION (PYRAMIDING)
k = input fixed amount / last price

If short on market AND number of bars since last trade >20 AND count of opened shares < (0.8*k) AND close < (positionprice/1.25) then
Sellshort ROUND((k)+countofposition) lots at close*0.999 LIMIT

FILTERS EXIT
	Condition5 = Average[AverageFast1,close] CROSSES OVER Average[AverageSlow1,close] AND Close > average[AverageFast1,close] AND Close < (2*close[AverageSlow1];
	Condition6 = Average[AverageFast1,close] > Average[AverageSlow1,close] AND close CROSSES OVER Average[AverageFast1] AND close<(2*close[AverageSlow1]);
	Condition7 = Average[AverageFast1,close] > Average[AverageSlow1,close] AND close > Average[AverageFast1] AND close CROSSES UNDER (2*close[AverageSlow1]);

RULES TO EXIT POSITIONS
If countofshortshares >= countofshortshares[25 bars ago] then
If Condition5 OR Condition6 OR Condition7 then
Exit short ROUND(count of shares /2) lots at market

If Short on market AND close < (2*close[AverageSlow1]) then
Exit short at Ratio*average[Period,close] STOP
