A simple Expert advisor based on Averaging and Flexible Martingale needed

Hello

I am looking for a coder who has experience in developing an Expert Advisor which takes trades based on averaging with lot sizes increasing according to Lot multiplication factor specified by me in settings

All positions will be closed when price retraces and hits predifined price above or below average price of all positions combined (In case of basket of buy orders take profit is above average price of all buy orders and in case of basket of sell orders take profit is below average price of all sell orders)

Details of input fields to be added will be given to coders who are interested in doing this job
