' Descreption: This indicator uses Stochastic with periods 8,3,3 and RSI 3 cross RSI 13 and 
'              it use a confirmation trend macd cross zero.
'              If both are crossing together then you shall view the signal to open position 
'              so you just need to open position.
'              This is momentum-type indicator so you know how to buy or sell in the right time.
