Laguerre RSI Multi-Time Frame

The Laguerre RSI Indicator is a modification of the well-known relative strength indicator or RSI. John F. Ehlers, the famous trader who created the Laguerre RSI, tried to avoid whipsaws (noise) and lag produced by smoothing technical indicators by applying a filter and some changes to the original relative strength indicator. The result is a technical indicator that is more responsive and has much less noise than the original RSI indicator.

The multi-time frame LRSI is used to have multiple RSI oscillators on the screen at once that are derived from different intervals. This allows the trader to see setups in multiple time frames.

Release Notes:

Updated to Version 3 compatibility.

Release Notes:

Updated to version 3 and fixed defaults.

Release Notes:

• Fixed repainting issues. Desired intervals greater than the chart interval will now show incremental updates. Let me know through the comments section if it is desired to add smoothing to help with the noise that is generated because of this.
  
• Added option to lock each of the intervals onto the chart interval to enable easy flipping between chart intervals and have each LRSI update accordingly.
  

Release Notes:

Fixed session security function call, forget that it needs the lookahead flag added for version 3. i.e.

• start = security(tickerid, rez, time, lookahead = true)
  

Release Notes:

Changed the main script window TF to 15m, updates complete for this cycle.
