1. System goes Long, if the StochK is in the oversold area (below 20) and StochK is higher than the last low(peak) of the StochK value (e.g. now the value 14, last time it was 12)
2. System goes Short, if the StochK is in the overbought area (above 75) and StochK is lower than the last high(peak) of the StochK value (e.g. now the value 80, last time it was 82)
3. The reversal level is 20% or 30 as absolute value
