Write some software

I need you to develop some software for me. I would like this software to be developed for Windows . A automated trading program (from here and out the EA) that works on the MQL4 platform and be able to automatically dicede when to take a trade, the size of the trade and when to exit a trade. The program would get all the needed information. Such as stock prices, charts ens. this ea will run on a 1 day graph. basically i want a ea that trades using : donchain ( 20 day ) The sma (14) . Mac D (14 , 26 ,9). when the pips break through the donchain resistance line 2 times ,when the sma 14 line passes through a rising pip and when the mac D 14 is above the mac D 26 , then only must a buy trade be started. the sell trade will be activated when the 3 conditions are met but in reverse ( donchain support line is broken through 2 times, sma 14 passes through a falling pip and the mac D 14 is below the macd 26.) a trailing stop and a stop loss will also be needed. the trailing stop will only activate when the 2 mac D crosses , sma crosses the pips , and will be 50% of the ATR ( average true range ) the stop loss will be the buying price - Atr. "" entering price - Average true range "" { buying market } && "" entering price + Average true range "" { selling market } the position sizing will be 3% of current account value per trade. There will be a maximum of 3 trades taken, all of which would total to no more than 9% please leave comments throughout the code so that I can understand what I must check when I do back testing on the program.   Conditions for entering a trade This is a mac D that uses the same values as the other mac D. When the histogram shape at the bottom is above proves to be the highest compared to the other charts , it must enter a trade but only if the histogram value is above 0.7. The chart with the highest gradient must also be chosen So the top 3 charts must be the charts with the highest gradient of the 14 day ema of the MacD and with a histogram value above 0.7.
