Well first I set my chart for candlesticks.
I initial look at the four hour chart chart first.
I set up the following indicators:
Bollinger bands (normal setting)
RSI (20)
MACD (6,13,9)
Parabolic SAR (.02,.002 and .05,.002)
Exponential MA 10
The ideal set up is when both SAR's change at the same time. That usually seems to indicate a very strong move. That doesn't happen too often though.
Something else that seems to work well is the following:
Say the SAR is indicating a down trend
You find the first down Bar that is entirely within the bollinger bands and under the 10 EMA.
Then you see if the RSI is under 50 (preferable under 45)
That point should be pretty close to the bottom and a big reversal should be eventually underway.
Now, let me stress HIGHLY, that these are hardly perfect. There have been plenty of times that they have underperforming or just not hit at all.
They seem to work though more often than not.
The reason why I think is that the rules are so specific that it keeps me out of the market most of the time.
Also, TA seems to work better on longer time frames.
Anyway, I hope this answered some of your questions.
