Limit order execution

[ogik]

Hello,

I had a questing regarding limit orders being executed on fast moving stocks such as "morning gappers" that pop really fast once the market opens.

I sometimes don't get filled unless I place a limit order +20c above the ask and sometimes more...For anyone that scalps morning gappers, what would be your strategy on placing limit orders that would get executed more often?

I love to use hot keys also, so just wondering how other people use limit orders when entering and exiting fast moving stocks?

For example I like to place a limit order on the ask +5c intra day. For morning gappers I usually place +20c on the ask (due to slippage).

Thoughts?

Thanks
