Does anyone have any ideas on how to build a filter that spits out long/short ideas of stocks in the same sectors based on the mean reversion principle. Or would anyone be willing to share some filters that they had success with in the past. Any help or advice to pull me in the right direction would really be appreciated. Thank you in advance

LOL!
Yes, it IS the same stocks because of the selection criteria:
MARKET IS NASDAQ 100
But one filter looks at the lowest values of CLOSE - LINREG(60) and the other filter looks at the highest values!!
BUY LOW, SELL HIGH!!

Any indicator with the name that ends with "bands", "channel", or "envelope" is supposed to spit out, or at least spit in the direction of, a mean-ass reversion solution to sending the stock back up towards the average. Bollinger Bands, Keltner Channel, Moving Average Envelope, to name just a few, are those that belong to the mean reversion camp. Would you mind explaining in detail what ure specifically looking for?

yes, nikoschopen, i would love to explain and maybe you can help me further: want i would like to have is a filter for market neutral pairs trading. a filter that helps me find 2 stocks in the same sector with high correlation that are at least 2 standard deviations away from the mean. for example going long citigroup (c) because it underperfomed the trend, and shorting bank of america (bac) because it outperformed the trend, with the hope that both stocks would reverse back to the mean (trend).
in a step further i would like to do this for an entire sector. for example build an entire portfolio of about 40 stocks (20long, 20 short) in the engergy sector or oil sector or transportation sector.....
for technical indicators i would use things like"
RSI, stochastics, bollinger bands, moving averages...
14 day RSI should either be oversold or overbought (under 30 or over 70),
entry point for the trade should be when the stocks are at least 2 standard deviations away from the mean.
any input is really appreciated, thank you

Here's a simple screener used to filter a possible pair from the same industry group. For the sake of simplicity, suppose the 20-day moving average is used as the mean. I want to find one leg of the pair currently trading above and the other below MA(20). In our example, you will find a value of either "1" or "-1" in the fifth column labeled "mean". A value of 1 indicates that the stock is trading above its MA(20); a value of -1, below its MA(20). Hence, you'll want to pair up those with a value of 1 to those with -1. Feel free to modify the industry and change MA(20) for any other indicator of ure choice.

nikoschopen, thank you very much for the quick reply and filter.
this is exactly what i was looking for, and a great start for me to play around and match potential longs with shorts.
it amazes me how fast you can build a filter like this.... how long have you been doing this...what is your background? after spending more time on this i am sure i will have more questions and i already thank you for your time and help
