I don't know who you're asking (it wasn't me who mentioned MACD or RSI) but in case you're asking me, my suggestions are:-
For MACD: use it as a bias indicator only, on very high settings, for example 30-45-25 or even 40-60-30, to bias you in favor of identifying potential long entries from price action only when the MACD line is above the signal line and both are rising, and in favor of identifying potential short entries from price action only when the MACD line is below the signal line and both are falling.
The advantage of using it this way is that it's effectively representing a longer time-frame within the time-frame from which you're trading, without any multiple screen complications, and giving you a good perspective of "longer term trend".
However you look at it, the standard 12-26-9 settings (which I think LauChoKun was recommending, at least in principle) have nothing to do with trading spot forex on any time-frame at all - they're just a historical left-over from the days of trading stocks on daily charts with a 6-day week (the "12" was the number of trading days in 2 weeks and.the "26" was the number of trading days in a calendar month of 4.3 weeks). Hardly a surprise that those aren't appropriate at all.
For RSI, personally I'd recommend using it only for "RSI divergence", and a setting around 20 or 22 periods can be quite useful for that: anything much lower and you get loads of false signals; anything much higher and the thing almost never fires at all.
But this doesn't matter much. My main point was that LauChoKun's advice was horribly inappropriate and unhelpful, for both the reasons I explained in my post above.
More education before trying to practice.
The idea involved in learning as you go along, especially by looking at what other forum members are doing, and using standard indicators in standard ways, makes it terribly difficult for people to succeed.
This is probably among the reasons why so many people fail?
If you look at how institutions are training graduate entry-level people to trade their money, I think you find something that's actually not nearly as difficult as people imagine to try to copy yourself. It's a whole different approach from what you see people talking about in forums, surely, but I think far more likely to be successful.
Apologies if I wasn't the person you're asking, Tommor.
