What does repaint mean?

[GeneHo]

At times, I do read from the forum that some indicator repaint signal. What does repaint mean? How can I tell if an indicator repaint signal? Will past signal stay? What I mean by past signal appeared on yesterday chart for an example.

A great example of an indicator that repaints would be the Trend Reversal indicator. If you watch it live, you will see that in most cases the signals will disappear if it doesn't work out within the next few bars. That's why you see there is a stop loss line added into the indicator. If the candle closed above or below that stop-loss line (depending on the direction of the signal) the arrow will disappear.

Generally, if you have an indicator that shows buy and sell signals on your chart and every single signal works out perfectly, then most likely that indicator is delayed or repaints. Looks great for backtesting but no use live.

@BenTen Hi does this Trend reversal Indicator work for trading overnight?

 

[BenTen]

@Billions By trading overnight do you mean the extended hours? It should.

From a coding standpoint, when does an indicator repaint in Thinkscript?

What are the most common reasons and how can we avoid that?

When you realize the indicator repaints....

Is there a way to turn off the repaint?

Repainting is the only way to know that you have finally reached THE high or THE low.

It declares, "Eureka!" on every lower low erasing all previous eureka's. Eventually, it actually does reach the lowest low and no longer repaints.

It has no way of knowing those false lows weren't the lowest low. They looked good at the time; until it continues downward and reaches yet another lower low. At which time, it says: "Oops" and it erases that previous false signal. It draws the new low with high hopes that this is The Low.
