slippage matter : im interested about subject about ECN broker playing things with identifying our EA and magic number , related to ECN slippage things

[Rachmat Sadikin]

im interested about subject about ECN broker playing things with identifying our EA and magic number 

i feel my slippage is little bit lower since im using different magic number on all of my EA, is it posible broker playing things from tracking my magic number??

If this magic number thing is could be the culprit also,

i remember somehow my EA from the old developer/programmer that curently gone away,

its already had randomizing magic number if im not wrong. can this feature in my EA wich i didnt know anything about the "hiding magic" number, really works on this broker nasty things?

it would be ok for me to do another project wich cost, if this matter is essential and did really exist (ECN playing dirty stuff from magic number, etc)

NB : 

I know they always said, its the Liquidity problem bla bla bla , we cant help but its our LP that accept your order how ever they can

I know some would say, move away to other broker, but this broker had facility that i do really like about.

Lets disscus the subject, any insight would be very appreciated.

And the ECN slippage things, would be good things to discuss too

like splitting volume each closing trade etc2

Thanks
