Drawing trendlines using BNPoint objects on a sub graph

Tutorial 105 is a TradeStation EasyLanguage tutorial that demonstrates how to draw trend lines using TradeStation drawing objects on a sub-graph containing an RSI indicator. This builds on the technique described in tutorial 104. One of the advantages of using this technique (when compared to TradeStation legacy trendlines) is that it is possible to draw the line to an exact bar. This means that this technique can be used on seconds, tick and other charts where a several bars may share same data and time (when expressed in minutes).

In this tutorial I draw trend lines between adjacent low pivots on the RSI plot.

This tutorial applies to TradeStation (but not MultiCharts) because it uses TradeStation’s new drawing objects.

Two potential ‘gotchas’

Gotcha 1

A BNPoint refers to the absolute bar index (zero-based) of the collection of bars in a chart. This is not the same as the BarNumber function or CurrentBar reserved word which count the number of bars available for analysis after MaxBarsBack. So to create a BNPoint for the current bar (BarNumber) would be:

NewBar = BarNumber + MaxBarsBack – 1;

Gotcha 2

Another issue that can cause what appear to be spurious results are the ‘Show empty daily trading periods for traditional chart types’ and ‘Show empty intraday session periods for traditional chart types’ settings.

If these are selected, the chart includes blank bars which ‘confuse’ the bar number for BNPoints. For example, in the following daily chart of IBM, the ‘Show empty daily trading periods for traditional chart types’ is selected.
