I am inquiring to see if other users may have worked out the below codes and possibly others; and to find out if there is a schedule for the future development of programmable Technical Indicators?

I ask this now because after converting a WLP4.5 script utilizing tests among Stochastic Oscillators (%K & %D); Linear Regressive Slope, and Crossovers to WLP5.5, I found that the coding would have been a world simpler had had the following pre-canned Technical Indicators and functions been available:
o StochD,
o StochK,
o Linear Regressive Line (with capability of having a Slope given,
o EMA
o Slope calculated at a specified bar of an EMA or Bollinger Band (either upper or lower).
o Bollinger Bands
o Sound files for code generated alerts.

The drag and drop Indicators are convenient in setting up potential analysis by inspection; however, a testing/integrated strategy requires access to bar data.

At this time I believe the LRL code has been worked out; however, I'll post my StochK&D once I get it validated.

I don't understand the question. These all are canned indicators and of course are included in WL 5.0. Hit Ctrl-F11, then expand Wealth-Lab Standard Indicators.
