Forex trading EA with exponential grid

I need an EA like the EA Black Dragon but where you set the grid not with multiplier but that the multiplier increases exponentially.
it would be great if you could enter the multiplier yourself for example:
first opened position x1.0
second open position x1.5
third open position x2.25
fourth open position x3.38
fifth open position x5.07
and so on.

There should be up to 10 positions for sell and buy.

The EA should also check itself whether it already has open positions, if you would have closed the chart window once or otherwise an error occurs.

actually a simple and short thing.

who has time?
