Keeping Your Chart Right-Justified
In real-time trading it is vital to keep your chart right justified, i.e., ensuring the right-most price bar is visible at all times. Failing to do so and looking at the wrong bar when trading real-money can invoke a panic response by the trader that results in erroneously closing a position or worse, placing a wrong order. This can easily happen if you are running several computers and are not always monitoring the chart being traded.
The following code shows you how you can right-justify your chart at system startup or from the Param window. A visible alert that changes the chart back ground color when the last bar is not visible is included.
The Alarm uses DateTime() to automatically correct for blank bars at the right edge of your chart. The code is kept explicit and you may be able to optimize it for speed.
