Market on open / close question

L

lasvegas_trader

Just finished developing a system that trades off of open/close price. Can I always expect to be filled at the official open/close price if I enter a MOO / MOC order?

0 slippage?

If you are buying first, yes. If you're shorting first, possibly not of course. NYSE.

Been tried by many, failed by most over the last few decades however.

You can short Nasdaq stocks at the open but not NYSE unless is uptick. You will get the single auction price BUT be aware that if your order is large in relation to the volume that is crossed at the open then you will be influencing the opening price and so will incur market impact losses. To get an idea of the volumes that cross at the open (for Nasdaq), take a look at
