Whew... I've been reading this thread for the past week off and on and I finally finished reading all 185 pages today. The journey it took was pretty interesting, starting out with the simple parabolic sar, evolving into a more complex system with ema, rsi, macd, and other indicators, and it seems like it has sort of ended up right where it started, that pure parabolic sar can work and that the other indicators didn't help as much as once thought. Dale, I have a few questions and comments about the whole thread now that I have read the entire thing...
they are listed below, I numbered them to make them nice and clear..
1. Many times during the thread, you mention the creator of the parabolic sar, J. Welles Wilder and a book he wrote, New Concepts in Technical Trading Systems. You mentioned that you currently use some of his systems, including one that gives you trades "almost every day". I was just wondering, are these systems you are using in this same book I just mentioned, or a different book?
2. It also seemed that you had more success with pure parabolic sar and other indicators created by Welles in the commodity and stock market indices than with forex.. am I correct? I remember many pages ago you mentioned soybeans and how it behaved very well with psar and how the comms and indices seem to "behave" better than forex when it comes to using psar.
3. Over the course of this thread, several different indicators were used to compliment pure psar, I have looked at many of them on charts and while some of them do seem to filter out some bad whipsaws, they also can keep you out of some good trades if you use them along with psar. ADX, MACD and the 50-day ema were a couple of the ones I looked at especially, did you ever come to a conclusion about which of these, if any, was most successful? Personally I believe that the idea of ADX is great, since it's supposed to keep you out of ranging markets where psar doesn't work well, but as you mentioned earlier in the thread, it didn't seem to work too well with forex.
4. Many times towards the beginning of the thread you talked about being careful with the "commdolls" aud, nzd, cad, and zar. You said it would be best to not take a position in these trades unless the commodity "agreed". I know that aud, nzd and zar are usually correlated with gold and cad with oil.. does a move in the forex pairs usually happen AFTER the commodity has moved one way or the other? This would make sense to me, I just wanted to confirm. Also, I found a good link showing currency correlations, not sure if everyone has seen these charts but they look beneficial to me...
5. I am interested in trading commodities and stock indices as well, do they require more capital to trade than forex? My forex broker is oanda and I can make trades as small as $1 but the only commodities available to trade are gold and silver.
6. Right now on my chart I have the parabolic sar with default settings (0.02, 0.2) 50 ema, and bollinger bands. I have noticed that, like the other indicators, the bands tend to keep you out of a lot of whipsaws if you only follow psar when the dots are outside the other bands, but you do miss out on some good trades when the psar dot stays inside the bands, but still lead into a good trend. I also noticed that the 50 ema does a good job showing major trends, but sometimes, especially in ranging market times, when the price closes alternating above and below the 50 ema several times a week, you can take some bad losses if you enter the trade. However, once the price gets further away (but not too far) from the ema or if the candle has closed above or below it 2 or 3 days in a row, this is a confirmation of a good trend. It does get you in late on many trends though. I believe this was mentioned before, but my idea was to weight the trades, so if macd and psar and the 50 ema all give you a good signal, maybe you can risk more on a trade than if say, just psar gave you a good signal.
Anyway, I think this is a great thread, probably the best I have read on the site and just reading the first 10 or 20 pages made me want to read the rest to get the "full story". I am also going to buy Wilder's book this weekend and give that a good read. While reading through this thread I went through many stages where I added this or that indicator to my chart because it was the new idea, I'm just glad I waited to read the whole thread before jumping on and getting a bunch of trades in

. I can only see this idea evolving and getting better, and I would love to contribute in any way possible... So many others have already and it only can improve things the more we have "on board"... Anyway, good luck everyone with your trading and I hope to soon join you all in business (right now I only have $50 in my oanda account and I am just trading 1 cent pips to try some things out so no big profts or losses for me!)
