Theory :

  • Ocean series of indicators were originally created by Jim Sloman (the theory) and Pat Raffalovich (the coder) - additional information can be obtained in Jim Sloman's book 

  • Natural market slope is an indicator that combines :

  • Natural market slope period linear regression slopes (weighted by appropriate coefficients) into a single "market slope"

  • Prices can be additionally pre-smoothed vi TEMA (triple ema)

  • Even though usually adding pre-smoothing adds lag, using TEMA in this case works very well (default values are using almost insignificant lag)

Usage :

  • As any usual slope / momentum indicator

  • You can use the color change of the indicator as an indication of momentum change

  • You can use the zero cross  of the indicator as an indication of "trend" change
