How would I add a chart button that toggles (adds/removes) a technical indicator with specific preferences?

Here is an example: assume we want to create a button that will toggle Pivot Point indicator lines on and off. First, add the Pivot Point indicator to your chart with the preferred settings. To create a toggle button for any indicator in your chart, right-click on the indicator and choose "Add Button" from the ensuing pop-up menu. The button will then appear in the chart. To test it, click the button and watch the indicator in question disappear and then return as you click.

How do I create a cumulative daily A-D Line for the S&P 500 (or any other custom group of stocks or symbols)?

First, create a quotepage which contains the group of stocks or symbols on which you'd like to create your cumulative A-D Line. Now download enough daily data on the quotepage to cover the desired period. In our example, we'll create an A-D Line on the S&P 500 from January 1, 2004 to present (August 20, 2004).

Once you've downloaded enough data, we'll need to create two custom indicators which will provide us with what we need.

The first custom indicator will have the following syntax:

(CL > CL.1) + (CL.1 > CL)

How do you display bid/ask dots/lines on the chart?

The bid/ask feedback has been improved since this tutorial was originally written. Instead of dots at the bid and ask, we now draw a vertical line from the bid to the ask price. There is also a small horizontal line representing the current price that protrudes left from the bid/ask line (this becomes an arrow when in "Presentation Mode").

In RTL how can I use the same technical indicator token multiple times within the same formula? Is there a way to use other RTL object names directly in the formula?

The RTL formula (syntax) checking process has been improved in several ways to facilitate entry of RTL scan, signal, and custom indicator formulas. The improvements are designed to facilitate entry of technical indicator tokens in cases where multiple tokens are needed for the same technical indicator. In addition, the improvements enable the user to extend the technical indicator tokens available for use in RTL formulas through the use of pre-defined technical indicator "presets".
