I know the principle of the strategy tester under NT8.
It reads the information as it comes, as if time were passing, and applies the indicators. Depending on this, he opens or closes positions.
If the indicator used is repainted and I place this same indicator on the chart at the end of the simulation, the entry points will be visually different.

Does TradingView work the same way?
Chat GPT tells me yes but mentions so many possible differences that the answer is not absolutely clear.
I can’t find this information anywhere so my question here.

This question because I found a strategy that gives “too good” results in the strategy tester.
In the comments it is specified that the indicator is repaint.
This should not pose a problem if the simulation was carried out as under NT8 and the results should therefore be valid…

Thank you for your details or URLs that would allow me to have the answer.
