GU_scalping is a simple strategy, it's only use EMA 9 and EMA 14 cross, for the filter I use rsi with 6 value. I use 15 minutes timeframe (v.2, for the v.3 I use 1 hour timeframe), basicly this strategy is trend continuation SHORT when oversold (RSI 6 smaller than 30, EMA 9 shift 0 smaller than EMA 14 shift 0 but SMA 9 shift 1 higher than SMA 14 shift 1) and LONG when overbought (RSI 6 higher than 70, EMA 9 shift 0 higher than EMA 14 shift 0 but EMA 9 shift 1 smaller than EMA 14 shift 1)
