Thread: Script to modify lot size of pending order

Hello dear programmers/guests,

I understand there's comparable thread/script described but there's a lot threads and that I ´m confused to find it. It would be great if someone could make me script or just post here .

How should it work: when set any pending order then order adjust to x percent (for example 2% and with stop loss 15pips) of equilibrium account

actual example:
account balance: 5000
risk percentage%: 2 percent
prevent loss: 15 pips (150 points)
pair: EUR/USD

result: 0.827 lot

Thank you if someone answer

thanks for reply,

yes I was afraid of the situation, I composed it not quite clear because of my bad english, I will try to write it more clearly

imagine this situation, pair EUR/USD: you have 5000#8364; equilibrium, 1% stop loss(SL=12pips=0.517 lots), however we win= profit 1% of equilibrium (50#8364;-RRB- (R:R=1:1)
2nd trade: now our equilibrium is 5050#8364; 1% stop loss (SL=12pips=0.522 lots) again win and we earn 50.50#8364;
3rd trade: equilibrium 5100.50#8364; stop loss 1% stop loss (SL=12pips=0.527 lots)


see these differences between lot dimensions per trade? And this I want to automate and loe any script onto it

If not clear let me know I will try more

EDITI start new trade only by pending orders

As far as I know, you can't Alter the Magnitude of the Existent pending order
It'd Need to be Substituted by a new order
