This indicator also implements the ACD methodology. It combines the opening range, Points A and C and levels to open a position from Points A and C. Thus, you can see the level when the position will be opened after waiting for a time equal to half the duration of the opening range, after Point A or C is broken through.
First you should fill in the text file with A and C values for each security that interests you, something like this:
Futures are indicated in the file by the first 2 characters (2 other characters associated with the expiration date are missing), and stocks by 4 characters. The symbol is followed by A and C values in ticks, separated by a semicolon. If you select a chart which symbol is not in the file, only lines for the opening range will be displayed.
You can change two parameters. The first parameter is the duration of the opening range, the default setting is 20 minutes. The second parameter is the number of days to display the indicator, the default value is 1 day. You can set any number of days (if it goes beyond the trading history, then the entire chart is covered by an indicator). The time frame of the chart must be a multiple of the duration of the opening range. Otherwise, the calculation of the number of bars corresponding to half the duration of the opening range will be incorrect. For example, if the opening range is 20 minutes, then the time frame of the chart may be 1,2,4,5,10 minutes. In case of switching between different securities, the indicator lines are updated.
An example of an indicator is shown in Fig. 4.1 for a 10-minute chart, with an opening range of 20 minutes, and A and C values of 10 ticks. As you can see in the screenshot, the levels for opening a position from Points A and C can lie quite far from Points A and C.
The evolution of the indicator for the current day as the market changes is shown in Fig. 4.2. At the first stage, only the opening range and the lines corresponding to A up and A dn are displayed. In the second stage, a short position is opened from A dn at 16 p.m. and two new lines appear - a thick green line for an open position and a thin blue line for point C, and a thin green line for A up has disappeared. In the third stage, a long position is opened from C up at 18-30 p.m. and one new bold blue line appears for an open position. Note that the distance between the green lines is greater than between the blue lines. This is because the market fell sharply after reaching point A, and after reaching point C it grew weakly.
