Scanning for increased range

Quickest solution is to use the Condition Wizard to build the line of code for the range. I have selected to use the study named ATR (Average True Range). This will take into account any gaps from one bar to the next and gives a much more accurate value.

Screenshot below shows how to setup the condition. The ATR on the left side is set to a length of 1 (this is the true range of the current bar). The ATR on the right side is set to a length of 14 (this is the 14 period average of the true range). All we have to do is copy the code generated by the Condition Wizard and append "* 1.25" to the end. Viewers can adjust this value to whatever value seems appropriate to them.

ATR("length" = 1) is greater than ATR() * 1.25

Just a few clicks of the mouse and a few taps on the keyboard. You can learn about how to use the Condition Wizard in the following video:

Here is the line of code that computes the position of the close within the range (high to low) of the candle, expressed as a percent of that range:

def percentOfRange = 100 * (close - low) / (high - low);

Now we can put those together and provide the full section of code that runs as a scan.

def increasedRange = ATR("length" = 1) is greater than ATR() * 1.25;
def percentOfRange = 100 * (close - low) / (high - low);
plot scan = increasedRange and percentOfRange < 25.0;
