What is the best EMA lines in forex chart? -

currently i m using 10 and 20 ema lines in a 5 minutes chart. the result is around 50% correct. is there a better ema lines to get better result? For best indicator for each currency, you have to test the indicator with historycal data. The result of the test will tell you the best EMA number fit with each time line. I use 10 and 20 SMA on 15 minutes and 60 minutes charts and I m glad with the results. Good luck no if you want a better result so go ema.com
