Oanda's Profit Targets

I trade with Oanda and overall I am quite with the happy with the service they provide. The wide spreads at certain times can pissed you off but thats another story. It will be a while before I can look at opening an account with a prime broker so I have to make the best of it until then. What I have noticed recently is,say for example I have a profit target set and the price reaches that price and goes beyond that price it can be 10-15 seconds before the profit target is activated and the trade is closed. I have a strategy where I sometimes re-enter after a trade is closed out. By waiting the 10-15 seconds I can sometimes be losing 2-3 pips which is annoying. How does Oanda's profit targets exits compare to other brokers.

I'm not noticing any delay on my end... sure it might take a moment to return filled but the price is usually without slippage from what I set it at..
