I would like to create a pseudo-candlestick data series that has the usual OHLC data fields, but the OHLC data are calculated based on other criteria. So I would calculate these new OHLC values for each bar and put them in this newly defined data series. Then I would like to plot these new candlesticks in a new pane above the regular pane showing the normal candlesticks streaming from the datafeed. In other words, 2 panes, pseudo on top, regular on bottom. Then execute the strategy on the pseudo data series. Can you point me to a script example that may have used similar concepts or WL5.1 functions and I will use that as a starting point?

See WealthScript Guide, Painting the Chart > Charting Multiple Symbols, for the how-to on plotting a synthetic symbol.

Thanks. Is there a new version of the Guide for 5.1 available for download somewhere?

On the regular price pane you can hover your mouse above the candlestick and it pops up the OHLC data for that candle. Is there a similar function in the scripting language that I could use for the synthetic candlesticks, or would I use the DrawText function and have to pass the mouse cursor location to the function for a similar effect?

For sure, HERE.

I don't think you'll get anywhere with DrawText since WealthScript commands are executed either manually or when a new bar arrives in streaming charts. However it seems like a good idea for Fidelity to implement this feature for PlotSyntheticSymbol. However it could have been disabled intentionally so that one wouldn't take synthetic symbol for actual Bars.
