Karen,

I'm still here occasionally and when I originally posted this filter I credited TRO for much of the coding ideas. I am a numbers guy so I tend to turn my code.into columns rather than chart lines.

Hello Ron !

1. I use end of day data.

2. I have no bias concerning Gap Up or Gap Down. That is where the filter is valuable. Rather than imposing my bias on the market I let the filter tell me which way to go. If a filter gaps down consistently I know not to go Long on the close but to wait until after the morning open for a better entry point. If a stock consistently gaps down and does not consistently fill the gap I know it is not a good daytrade candidate to fade. Likewise, if a stock consistently Gaps Up I can look to buy the close, especially when it has Gapped Down the last few days. These type of stocks will often revert to their usual behavior. I use this filter to not only trade gaps but to get better pricing on Swing Trades by buying at the better price by using it's Gap tendencies.

3. Depends on the type of trade. For a Daytrade I often will trade as little as a 0.25% Gap. On a Swing Trade the Gap I prefer would be at least 0.50% and larger would be better. Your style of trading would dictate.

4. For entries in general I screen for Technical Signals. I have 5 Signals I use and have developed criteria for each signal that I look for that has backtested profitable. I only trade when the ETF or Stock meets at least one Signal and preferably more. When my Filters flas 3,4 or 5 out of five signals at the same time I have a very good chance of success. For me, Exits are much harder. For years I have left too much money on the table. I would be afraid of a reversal and then bail on a trade right before it reversed and becam a big winner. Finally I realized that this is just my personality and that I would never be comfortable with longer term trading or Investing. Now I devise systems that go for higher win percentages and smaller targets. This fits me but would drive many traders crazy. Everyone is taught to let your winners run but for me it never worked. I became much more successful when I faced the fact that I could only successfully trade a system that I was comfortable with. For example, last month I was successful on 91% of my trades. Obviously they were for smaller gains. I rarely gain more than 1% on a trade and I never hold a trade more than a few days.


I hope this answers your questions. Actually the Gaps are a very small portion of my trades. The vast majority are mean reversion trades based on Technical Signals but automated through the filters. I'm an old retired guy who has narrowed his trading down to 2 or 3 systems that work for me and I try to make a few bucks to supplement my retirement. For me it comes down to the Math and developing filters that tilt the odds in my favor. There are 20 different ways to trade profiably but it has to be a way that fits you.


Best Wishes,

Marco

Here is a Gap fil,ter I have used for years to gather info on Gaps. This filter is one I use on ETF's but you can adjust the criteria to fit your needs. I have developed different systems based on the info obtained from this filter. I pulled this info from TRO and many other traders over the years and adjust the criteria to fit my trading style. Simple but informativ
