I tried to use EMA @ 2550100 based on the strategy of another trader but found it very risky.
The EMA's move to quickly a enter signal to an exit without any real pip gain. Even combining them with Stochastics P SARS B Bs does absolutely nothing on a 5 min. chart except throw away money.
More reliable to use the EMA's with P SARS Stochastics on a 1 hour with a 15 min. verifier.
that's about all I know about trading....
