slippage has no effect !!!

[Oktay Kaube]

When i began testing wih MT4, I mistake bid for ask at a long position, but i used a slippage of 100, just for securing the success of the opening-process.
Anyhow i got the 129-Error (Invalid price) ! After exchanging bid with ask the EA worked well.

The same problem is occurring in my current project: slippage doesn' t have any effect, but the direct manipulation of the price-parameter at OrderSend works.

Could it be, that the execution of slippage is broker-dependend (I'm using a MIG-Demo - MIG Investments SA - Account) ?

Does somebody else noticed this behaviour ?

Price must be real, not calculated! Slippage allows You to avoid requote
