PowerSM modification

I need the attached EA PowerSM to be modified.

What is does now:

1. buy or sell upon a first signal, which is set in the parameters.

2. if the trade turns out to be a loss, the EA trades in the opposite direction with twice the lot size.

3. if the trade turns out to be a win, the EA goes back to the first step

What I want the EA to do:

1. Option to set first trade (buy or sell)

2. if the trade turns out to be a loss (eg. stoploss 100 pips), the EA shall go in the same direction with twice the lot size.

3. After a trade becomes a win, the next trade shall be in the opposite direction.

So again as an example:

If EA buys with TP and SL 100 and lot size 0.01 and looses, then I want it to buy 0.02. and if it looses again, then it should buy 0.04 and so on.

If EA wins, it shall sell 0.01.

Quite easy actually ;)

Oh by the way, it is a MT4 file and should stay that way.
