On this Library you cand find a shortcut for some indicators and just import them into your source.
Each indicator has its own input and output parameters and they are prety much self explanatory. :D
This is the list of the present indicators you can use with this library:
*Function_Adx()
*Function_Atr()
*Function_Mfi()
*Function_MovingAverage()
*Function_Sar()
*Function_Rsi()
*Function_StochasticRsi()
Have fun!!!
