Need to change the size of my lots

Hello,
I need the size of my lots increases when my second orders opens and my third.
and when I close all my orders manually it starts again from the beginning. like a martingale.

example:

I enter the value 0.01 lots for the first order. 0.02 for the second order and
0.05 for the third order. When my expert is active he opens an order at (example) 1.3542
and what I would like is that when a stoploss or takeprofit is hit he opens the second order 
at 0.02 lots and when my takeprofit or stoploss is hit he opens a third order at 0.05 lots.
and if I close everything manually, everything starts from the beginning 0.01 lots then 0.02 lots 
then 0.05 lots ect.....
