Market Execution-questions

 
Hi All,
On Market Execution…
Which functions are useless?
1)Open price could be any price on the market.
Broker is making decision.
2)Slippage is useless.
3)Time execution-useless.
4)Spread is useless.
Which next?
Thanks
Fxman
 
Give up then.
 
I'm using bridge between MT4 and Currenex.
U can not use Instant execution. Mt4 is not ready for ECN.
I'm trying adjust my EA to this platform.
Why I'm asking these questions.
Slawa, what is is your answer?
