I want to convert my Strategy into MT4 EA

I need a developer to create a cross over moving EA  My strategy depends on the complete intersection of the two moving averages:10,200. if the order is from the top to bottom 200,10 it is a SELL conversely,it is a BUY order transaction. the stoploss and take profit,it is by thr previous top and bottom of the trade,and the ziczac indicator can be used the percentage of the distance between the previous top and bottom of the trade,we rely on it to determine the stoploss and take profit.EA must be working on all time frame,EA must be working on all forex,stocks,crypto,gold lotsize is fixed or automatic. i hope you understand the moving average cross over please..EA must have the parameter to change the moving average cross over thank you.
