Definitions of slippage

[tcima]

Hello again,

Could anyone elaborate the definitions of the "Slippage" in the Trade History window?

I guess that it is the difference between two prices: the ones at the time of order trigger and actual execution.
Positive slippages are always good, regardless of the types of orders: long or short.
Am I correct?

You are right. The difference is in position value (price * quantity)  rather than price.

Thanks for your quick reply!

My slippages of executions have been mostly positive.
There seems to be no problem with the algorithms of your system and the IB's APIs.
