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. SampleRTX parameters include two moving averages and the drawing includes a marker to denote crossovers of the two moving average lines.

RTL - Investor/RT Language

RTL is the Investor/RT Language, a formula language for composing trading signals, custom indicators, and scans. RTL is an end user language, designed to be used by those with little or no programming skills. RTL is used to write a formula. A formula may be a true/false condition, e.g. CLOSE < MA, that determines whether some condition is true or not for each bar (a signal) or the last bar (a scan). A formula may compute an arithmetic result, called a custom indicator. For example: MA ( HIGH - CLOSE ) computes a moving average of how far an instrument closes from its high. As you can see, RTL is more expressive, simpler, and easier to use than other market data languagues.
