If the previous trade is positive, it doubles the volume

Hello Everyone,

In 1st place, sorry for my English.

My ideia is that every successful trade, bot double volume of previous trade. If the trade is unseccessful, it returns the inicial volume.

Example:
Trade 1: Buy 0.01 (successful)
Trade 2: Buy 0.02 (successful)
Trade 3: Sell 0.04 (successful)
Trade 4: Buy 0.08 (successful)
Trade 5 Sell 1.16 (unsuccessful)
Trade 6 Buy 0.01 (successful)
(...)

Thank  You
