Is there a filter that can detect gaps a day before they occur? Either up or down gaps. I will be very glad to see that. Thanks.

A gap isn't a gap until it gaps. If someone can code that, I would love to see it too. Here is an old filter I wrote a long time back that you may edit til your hearts desire. My attempt here was trying to code for stocks that had a frequency within their 14 day LRC channel to gap down then fill but I did not continue with it nor did I use it much so I cant tell you how well it performs. I few times I did find stocks that that had a frequent occurance (var5) that would open below its lower lrc and I would enter good til cancelled option orders for standing days hoping it would repeat this gap down at open and get fills at a cheap price. It worked a few times to my benefit but I have not used it for a while. Maybe you can expand on this or it may provide you another idea.

open below Bottom Linear Regression(14,1) 1 day ago
set{var5,count(open below Bottom Linear Regression(14,1) 1 day ago,30)}
add column var5
slope of Linear Regression(14,1) > .1
price > 5
draw Linear Regression(14,1) lag 1 day
Day Change >

Hope it helps.

I'll use WH on September 7, 2010 as an example.

This filter finds the tall white candle.

Look 1 day before AND look 1 day after the tall white candle.
Do you see the gap?

Now remove the OFFSET and try some other days and stocks. See the constant pattern.

Any ideas how to use this filter for profit?

Perhaps, we wait for the breakout:
BULL: trade occurs if a candle low clears the high of the filter candle.
BEAR: trade occurs if a candle high clears the low of the filter candle.
Consider a no trade range occurs as long as an overlap is present.

You can't predict the future with 100% accuracy but you can report on WHAT HAS HAPPENED!

That is why I write statistics filters:

Knowing the frequency that gaps have occurred, the average size of the gap and the how often they filled during the last 100 days gives you the information you need to trade gaps.
