The best filter to code on higher times frames for a strategy

A am coding a general class for filtering the trades. I have several possiblities and want to know from you if U have other ideas...and a short selection...not important but interesting...so I hope 2 here from U guys!
- a slow MA X is under a fast MA Y on daily base!
- price move the last X days Y pips up/dn
- the 2 daily candles before have the buy/sell direction
- price is more near the daily support than the daily resistance for buy and sell vice versa(or only maximal X percent away)

What do you think?

Did you tried Bollinger Bands, or any other channel? Some more ideas, True TMA and Regression Channels. Another one way to enter on retraces are the Fibonacci retracement levels. Have a great week!

As Js3mwtRC has said, you may try with Bollinger Bands or any other "channel-indicator". But think about the parameters you will use. The more paramters you have, the more difficult it is to optimise your strategy, and eventually you may end up overfitting. Therefore, I would use your last option: calculate the difference between the price and the daily support and resistance.

IMO the best analysis for longer TFs involves macroeconomics. But since this is unavailable for an EA, and you must stay within the bounds of TA, then I would say that it depends on what your strategy is:

-- If it is trend following or momentum based (i.e. buy strength/sell weakness), then I would use strength/weakness analysis to choose the pair/instrument/direction (pair strong currencies against weak ones). You could use an indy like PSA as a filter. Or you could test strength for a single pair based on the alignment of multiple MAs. If the trend is strong, and supposedly sustainable, timing of entry becomes less important, but in my experience entry on pullbacks works better than breakouts.

-- If it is counter trend or mean reversion (i.e. buy weakness/sell strength), then I would look at supply/demand zones as a primary filter, followed by overbought/oversold, for which Bollinger bands are as good as anything. Look for possible reversal candles at S/D and/or OB/OS areas, or swing failure patterns.

Thanks to all of you!
