Kind of martingale ea wanted for testing purposes

Hello programmers. I would like to run a simple ea on demo account and see can it make profit consistently and not blow up.

Idea is to buy 0.01 lots with equal tp and sl when price is above moving average say 200ma. and sell when price is below the moving average.

if a trade is a loss it would simply double the last losing position and open new order after new candle open. (buy if its up moving average and sell if its down) and set again equal tp/sl say 10pips.

when the trade is winner it will open smallest position again 0.01 and start the cycle again.

it would be nice to have able to customize the starting lot size, the moving average period to follow and sl/tp values.

Thats it.. i hope someones interested to build this up.
