Thanks miro, this tutorial I am looking for

@l-andorrà that the problem, I fill constant like lot, multiply, etc but how to connect to block

I have EA switch martingale and regular martingale already, but both have problem if market sideway (bad for switch martingale) and if market trending very bad for EA regular martingale.... so I have idea to combine it, and I am sure this will work good

Hai, can somebody teach me how to make EA mix switching and regular martingale ?
on menu :
Select Number : 0=Buy 1=Sell
Start OP : 0
Lots : 0.01
Take Profit (TP) : 20 (pips)
Step : 20 (pips)
Change strategy : 6
Maximum OP : 10
Magic Number :12345

the rule :

1. choose number 0= buy, 1= sell
2. if fill 0 (mean buy) , EA start buy first with 0.01 lots if positif will take profit (TP) 20 pips and open buy again.... if buy win 2 times next open is sell (if sell win 2 times change buy again)
3. If fisrt order (buy) minus as big as step (pips) will open order sell 0.02 lots and closed first order buy 0.01 lots
4. if second order minus again as big as step (pips) will open buy order 0.04 lots and closed order sell 0.02 lots.... and will replay until reach change strategy
5. if reach change strategy (level 6) will open buy 0.32 lots (because level 5 is buy 0.16 lots) and closed buy order level 5( buy 0.16 lots)
6. if in case position still floating will open order level 7(Buy 0.64 lots), level 8(buy 1.28 lots) , level 9(buy 2.56 lots) and level 10(buy 512 lots) .... after reach level 10 (maximum OP) will stop trade and waiting clear position (take profit).... Take profit follow the last Open position and if last level postion (example level 10) reach take profit , level 6,7,8 and 9 will closed together and start early again.
7. Ea can be used for forex (4 digit and 5 digit) and trading gold

thanks for help
