Default highs and lows

[tstrader]

On Thinkorswim, when using the 1-day, 1-minute timeframe, I’ve noticed that chart bubbles indicating new highs or new lows don’t always appear consistently. For example, if the price drops from $3 to $2, the chart might only show a bubble at $2 but not at $3. The same for highs. What determines when these bubbles are displayed? Is there any documentation explaining the logic behind this, or a way to customize their behavior?

My goal is to understand how it works so that I can create a study to determine where the high and low levels are for analysis purposes.

@tstrader In Thinkorswim there will only be one High or Low for the length of the specific timeframe... For example, on a 1Y 1D Chart there will only be one High and one Low... The same for a 3D 5m Chart, only one High and one Low... If you want to see more High's and Low's you would need to use an indicator... I see historical High's and Low's by having my customized Support and Resistance indicator on my Charts but it only plots lines not price bubbles, although code could be added to show that data...

I hope this addressed your concern...

On a 1 minute 1 day chart i dont see one. It randomly comes up at some point in the day. What is the logic behind it that makes it appear?
