Stochastic Momentum Index

Developer: FXCM

Stochastic Momentum Index (SMI) displays the location of the close price relative to the midpoint of the last high/low range, compared to the close relative to the recent high/low with the Stochastic Oscillator.  If the close price is greater than the midpoint the indicator is above zero.  If the close price is less than the midpoint then the indicator is below zero.

SMI consists of two lines; the moving average of the SMI and the SMI.

The most common method of using SMI is to look for buy trades when the SMI falls under -40 and then rises back above through -40.  Sell trades are looked for when the SMI rises above +40 and then falls back below +40.

This indicator was developed on FXCodebase*.

  • Period_S: Number of periods used in the second MA to calculate the SMI Moving Average
