Expand existing Expert Advisor with additional functions

I want to expand my existing Expert Advisor with the following functions.

1.MARTINGALE SETTINGS:

For martingale I want to be able to set lot multiplier.

I'll leave the rest to you

2.DRAW DOWN REDUCTION SETTINGS:

If the first buy position at 0.01 lots went negative and the martingale grid has reached the 8th position, it will wait for the market to retrace until the 8th position goes in the money for the same amount as the 1st position is negative.  The EA will then close both the 1st and 8th position simultaneously and therefore cancelled the loss out at plus 3% more profit than the loss, leaving the rest of the trades open to either hit TP or if the market reaches the 8th trade again it will repeat the same action.  This strategy is to lower the draw down while the EA is waiting for the market to retrace and hit TP of the whole basket.

I want at least the two settings for the rest I'll leave it up to you.
