| Filter Exchange · "The Super Passband Filter" by John Ehlers | |
| mktmole msg #129581 |
7/4/2016 10:11:47 AM Any efforts to code the below from anyone in the SF Community would be much appreciated. tks, mm - - - - From Stocks and Commodities Magazine July 2016. "The Super Passband Filter" by John Ehlers. This PB oscillator seeks to PB out both high and low frequencies from market data to eliminate wiggles from the resultant signal thus significantly reducing lag. This PB indicator achieves this by using 2 differenced EMA's of varying periods. (40 and 60). Trigger points for the PB oscillator are added with a RMS cyclic envelope over the Signal line. Output of the PB waveform is calculated by summing its square over the last 50 bars and taking the square root of the averaged sum to create trigger levels. Buy when PB crosses above its -RMS line. Short when PB crosses below the RMS line. This EMA calculation is significantly more reactive than the standard EMA or Wilder's EMA. Standard EMA formula found in most software is: α = 2/(N+1) standard smoothing factor where "N" = the period. Using N=40: α = 2/(N+1) = 0.04878, and (1 - α) = 0.95121 Ehler's Super PB Filter formula uses a smoothing factor of 5/N "period". α = 5/N Using N =40: α =5/N = 0.12500, and (1 - α) = 0.87500 |

" very noticeable keystroke delay, all keys, inc Delete It would be nice to have a "Clear" scan text button ) hope this helps |
