Hi Kevin,
Do you have any ideas why there haven't been any new stocks to buy on this filter since 6-24?
Usually there are a few every couple days and I just want to make sure I didn't do something wrong. Have you had any to buy since the 24th?
Thanks!

Your filter is correct there has been nothing since the 24th. Just the nature of the market conditions is my guess.

No, that is correct. There have not been any buys signaled since 6/24. That is not necessarily a bad thing. Probably reflects the ridiculous move up last week made by the S&P. The system saw this as a time to sell into strength.

Due to the last correction many stocks trade near their 200 MA. Requiring that they also are near the lower BB weeds out a lot of candidates. If you remove the "close is above 200 MA" syntax there are stocks returned. The question is how the backtest holds up without the above 200 MA requirement.

Why would you mess with a well-tested system just because it is telling you to stay in cash? Maybe it's right???

Kevin, I don't have time to get into your analysis, etc., but John Bollinger in his book on Bollinger Bands said that actually stocks fell outside the bands 5% of the time when you set them to 1.8 instead of 2.0. I don't know if anyone else has mentioned that in this thread, or if it makes any significant difference to your work. Cheers!

Hi Kevin,
I never got an exit signal for SJM but your performance showed as closed on 7/1. Even when I do a backtest, it shows as still open.
Thanks!

@jkinghome - Kevin's stats closed out all open positions to let you know how they were performing up to that point. SJM hasn't been triggered to close the position yet, so it should still be an open position if you're trading off of this filter.

Why would you mess with a well-tested system just because it is telling you to stay in cash? Maybe it's right???
Quote from your opening post:
"This still returned too many stocks, and during market corrections the system took some big hits. So I simply added a criteria that included “close above MA(XX)” for each stock, where XX was 50, 100, 150 or 200 days. This hopefully keeps you out of taking long positions on stocks that are tanking (keeps you “buying the dips”).
This definitely helped, and the system dramatically beat out the ^SPX, but the equity curves were still choppy and the system called for a lot of trades. "
Apparently your choice for a close above the MA syntax was not the part of the filter that you used the best of your skills and talents on and I think it would be interesting to see what improvements can be made here. After all you were basically looking to weed out stocks that are in a downtrend.
