it’s my strategy.i fund my trading a/c with only 2% amount of my investment capacity amount.if it goes wrong, i’ll loss $400 and will fund again with $400.but if it goes correct my a/c will be $800 and next trade will lot size will be $2, And if 2nd trade goes ok my a/c will be $1600, and then i’ll withraw $800…and 3rd trade lot size will be again $2.because my initial deposit is $400.
