Indicator based on Candle Timing

[lazdubrocq]

Has anyone tried creating an indicator that marks on the candle bar the price after a certain time? IE... I want the an arrow drawn on the candlestick indicating the price that printed at exactly 10seconds after the candle open. Ideally something similar to the arrows drawn indicating where you take an entry or sell.

Hello lazdubrocq,

Thank you for your post.

You can add a 10 second series and trigger actions on that series using a BarsInProgress check.

Or, you could use a C# timer by using TriggerCustomEvent() to trigger a price check after 10 seconds. Please see the help guide page for a code example:

This forum post also includes example scripts using a timer:

Use one of the drawing methods to draw an object of your choice on the chart, like an arrow or text.

I would like the check to only occur once on the 1minute candle and only on the first 10seconds.

Hello lazdubrocq,

You could do this by adding a 10 second series, which will update OnBarUpdate with BarsInProgress 1 every 10 seconds, and use a set of bools to trigger the action once per bar. (Meaning check if the bool is false to trigger the action, and when the action is triggered set the bool to true. Reset the bool to false when the primary series BarsInProgress 0 updates (or is the first tick of the bar).
The advantage of this method is that this could be backtested.

Or you can use a C# timer that elapses every 10 seconds that is enabled on the first tick of a new bar, and then disabled when it updates after 10 seconds.
This would only work in real-time.
