Add feature ILAN Expert

Hi, my friends.

I want to add feature ILAN Expert. Ilan is martingale expert and I want to add some functions. All features must be work same and i want  to add only 2 feature..

I want to add this 2 functions: 

- ADD maximum trade size... Ilan open lots with multiplier. (ex. 0.01 - 0.02 - 0.03 - 0.05 - 0.08) When reach maximum trade size, I want to ea will continue add fixed lot... ex. maxtradesize=0.12, when expert reached 0.12 lot with multiplier, Ea will add 0.12 always with next grid steps... (ex 0.01 - 0.02 - 0.03 - 0.05 - 0.08 - 0.12 - 0.12 - 0.12 - 0.12 - 0.12 - 0.12 - 0.12 ) Of course calculate take profit which is still in EA...

- ADD grid size multiplier.... Ilan has grid size step. ex. grid size 3 point and ea add new trades every 3 pip. I want to multiplier this. example grid multiplier 2.... when opened first trade, 2. trade 3 pips, 3. trade 6 pips (3*2) , 4. trade 12 pips , 5. trade 24 pips. 

another examlple: example grid size 2 and multiplier 1,5 .... when opened first trade, 2. trade 2 pips,  3. trade 3 pips (2*1,5) , 4. trade 4,5  pips (3*1,5) , 5. trade 6,75 pips (4,5*1,5) 

-Also EA have maximum open order, it must be still work... (maximum open order 20, if ea reach 20 open trade, EA will not add more trades... wait TP,)
