Order placement

[superfuego]

Help!

Suppose I have 3 times, t1, t2, and t3, with t1<t2<t3. If I expect the price change from t1 to t3 to be positive, but I can't buy until t2, how should I place my order?

t1 to t3 is about a day, while t1 to t2 is about ten seconds.

I'm a total noob about this. My thoughts are:
1. limit order at t2 for the better of the price at t1 and the price at t2.
2. Market order at t2.

Any idea you have I'll greatly appreciate, thanks.

Is my question just stupid? Or does it not make sense? I'm hoping someone has advice for me. I've developed a system that relies on closing prices, but takes 10 seconds to run the code, so I can't quite buy at the closing price. Should I just not worry about it? That's a restatement of the question.
