I am trying to scan for stocks which gapped up or down today morning.

For example.. If something closed at \$10 yesterday at market close and it opened at \$10.50 this morning.

And i would like to get the same result at anyttime during the day. as i know GAPS can fill up or down.

Thanks

Dipan

If you just need the close to be different than the open, than you could use the following condition formula in a daily time frame.

`C1 <> O`

If you needed the open to be say at least \$0.10 different than the previous close.

`ABS(C1 - O) >= .1`

If you need the open to be at least 1% away from the previous close.

`ABS(O / C1 - 1) >= .01`

If you need the open to be at least \$.05 above the previous close.

`O >= C1 + .05`

If you need the open to be at least 2% below the previous close.

`O <= .98 * C1`

The exact formula is going to depend on the specific definition of the gap.

Thanks for the quick response..

This leads me to another questions..

I would think

C1 <> O means... close of previos day is not equal todays open..

and

O <> C1 means .. today's open is not equal to previous days close..

When i do both of these , i get differnt number of results on the same watch list?

Not sure why..

You should not get a different number of results when scanning the same WatchList in a daily time frame once the market has opened. Are the time frames both set to daily? If so, please contact technical support.

How would I write a scan for a GAP where the Open is Greater than the previous close. In addition, Open is Less than the previous close.

The open just being greater than the previous close is the following.

`O > C1`

While the open being below the previous close would be the following.

`O < C1`
