SampleRTX (RTX)
A sample RTX extension that draws a trendline showing the maximum price excursion within the visible portion of the chart. Zoom the chart in/out using mouse wheel and the trendline will redraw for the visible bars. Changing periodicity also affects the visible bars; the SampleRTX will adjust to new visible bars of the new periodicity. For those interested in RTX development, source code is provided for this RTX in the InvestorRT\rtx\lsSampleRTX directory.
