Condition Wizard: Offset and Within settings

I have explained and demonstrated both of these in various videos and in the forum it is nearly impossible to describe them any more clearly. The best solution I can provide is to direct you to the language resources published for Thinkorswim.

The "Within" parameter is explained here:

And when adjusting the "Offset" parameter in the condition wizard that setting actually gets converted to "bars ago". And the explanation for that is here:

https://tlc.thinkorswim.com/center/reference/thinkScript/Reserved-Words/bars

Here are some examples to help explain this within the context of writing custom chart studies and scans...

The "Offset" parameter must be a positive integer value and it works the same way as the index syntax. Such that the following line reads the close value of the previous bar:

def previousClose = close[1];

Which is identical to this:

def previousClose = close from 1 bars ago;

And is the same thing as setting the "Offset" parameter to a value of 1.

The "Within" parameter value must also be a positive integer and its value is used to determine if a true/false condition was true "within" the span of X bars ago. With "X" being the value you enter for the "Within" parameter. For instance the following statement will return true if there was a green candle somewhere within the most recent 5 bars:

def greenCandle = close > open within 5 bars ago;

It is the same thing as building a condition for "close", "greater than", "open" and on the right side of the condition you set the "Within" parameter to  a value of 5.

Here are a list of videos in which I provide real world examples and clear explanations of these parameters:
