Requotes in your favor

I was testing new trading system on five brokers. System was placing up to fifteen trades a day. I had requotes, nothing new, but I realized, that almost all requotes were not in my favor. Hold on a second! Requote should be something like flipping a coin. In fact, with the brokers, it works only in one way. Broker's way.

what are requotes?


what interest does a broker have in ones trades. however, I am not so sure they would tell you the truth of their interest.

If the trend is in your favor you will eventually have more negative then positive slippage because market has a bias to that direction. If your system enters on breakout negative slippage almost always with retail brokers. etc. Since routing to the order matching server in the bank and your broker serves has additional lag in ms there is a chance latency arb just because of that so in the end if you don't provide liquidity either way you could/should have a negative slippage expectancy. Especially since banks have last look option.
