According to the Technical Indicators page, many of the Indicators are capable of accepting an additional "expression" in their parameters.
For example, the Bollinger Bands section uses this description in part:
The values of the upper and lower Bollinger Band lines. The bands are calculated using the values of the given expression, such as “close”, “volume” or “rsi(14)”.
Upper Bollinger Band (Upper BB)
Syntax:
Upper BB(nPeriods, StdDev, exp)
So this means that you could scan for the Upper Bollinger Band(20,2) of the RSI(14) in the example. and [Upper BB(20,2,RSI(14)) > ??]
Just something to keep in mind. I haven't tested all of these indicators in this manner yet to see if they actually work as expected but,
according to the Technical Indicators page, the following Technical Indicators are capable of accepting an additional "expression" in their parameters.
