Description
Force & Resistance acceleration using a tripple weighted moving average
For references here ths is a change to the original snake force indicator. With one difference and one addition.
- Indicator uses the HULL average which is tripple weighted instead of a standard weighted average.
- An additional setting has been added to set the periods of the HULL average. the snake force implementation has a default period setting of 24 and a hard coded value of 6 ( 1/4 of the periods ) as the period setter for the moving average. This implementation allows both periods to be set.
The thinking behind the tripple weighting is to make this a more relevant indicator for higher frequency scalp trading.
An interesting Robot algo might be to create a trade signal based on the Force or Resistance rate of change.
All thoughts or opinions are welcome.

Yes, it repaints the last 6 candles. Using future values it must repaint and there is no nrp-version possible, at least not without making the indicator lagging heavily and that would make it pretty useless.
