Hi,

First, I'm wondering if it's able to check pre-market and after hours price action with my current account? If so, how to write a PCF to scan the pre market gap? so 2% (up or down) to previous day's close price?

Thanks in advance!

This is not currently possible in TC2000 as there isn't a way to scan or sort based on the pre and post market data.

Thank you, Bruce!

I'm looking for a scan for gaps, I found there is a "gappers" preloaded scan, can you elabrate how to use it please? Or, where can I find the instruction on it?

I want to find the gap between previous day close and today's open, if it doesn't work on pre-market.

The built in gappers scan checks for either a gap up defined as the low being above the previous high, a gap down defined as the high being below the previous low, or both.

If you want to check for the open being above the previous close.

O > C1

The size of this gap is the following.

IIF(O > C1, O - C1, 0)

If you want to check for the open being below the previous close.

O < C1

The size of this gap is the following (expressed as a positive number).

IIF(O < C1, C1 - O, 0)

If you want to check for either.

O <> C1

The size of this gap expressed as a positive number is the following.

ABS(O - C1)

If you wan the value to be positive for a gap up and negative for a gap down, you could get rid of the ABS() function.

O - C1

Thank you Bruce!

As I put it in my EasyScan, can you elabrate the Edit Condition here please? I remember once I chose "Gap Up" with some settings, it showed up all the gap down patterns instead gap up, I don't know why.

I have no idea why it would show you gap down if you chose gap up either. Please contact technical support.
