I use a SL of 30 Pips, that seems to work well at least in demo testing, the best (4) curriencies appear to be GBP, CHF, JPY, & NZD. EUR/USD seems to have a few whipsaws and breakouts are not always clean. If you use Yaniis Straddle and Trail good settings are SL 30, TP 60, Trail 20, Break Even at Pips 20 and Lock Pips 10. (15 Min Chart First range breakout only)
