Scaled Normalized Vector Strategy

This is a scaled Normalized Vector Strategy with a Karobein Oscillator
Original: Drkhodakarami (

Repainting: in general there two types of repainting:
* when the last candle is constantly being redrawn
* when the indicator draws a different configuration after it has been deactivated/reactivated, i.e. refreshed.

The former is a natural behaviour, which presents a constant source of frustration, when a signal directly depends on the current market situation and can be overcome with various indirect techniques like divergence.

The latter suggests a flaw in the indicator design.
Unfortunately, the Normalized Vector Strategy is repainting in the latter sense, although being really promising. Would be nice if our community suggests a solution to this problem ))
As it is this strat should be refreshed each time a decision is being taken.

This strat consistently performs with high accuracy, showing up to 96% scores. Here are some of the best parameters:
TF Lookback Performance (ca.)
1m 13 92%
3m 34 92%
5m 85 92%
15m 210 90%
30m 360 89%
1H 1440, 720 94%, 87%

The Karobein Oscillator has an intrinsic sinusoidal behaviour that helps in determining direction and timing. It does not repaint.

in tradingview documentation it says barmerge.lookahead_on is not suited for backtesting, would these results be similar if not use barmerge.lookahead
@MRKCHAMPION, they will be worse. Trying to resolve this...
@MRKCHAMPION, Right. The statement for barmerge.lookahead_on is as follows:

"Merge strategy for the requested data position. Requested barset is merged with current barset in the order of sorting bars by their opening time. This merge strategy can lead to undesirable effect of getting data from "future" on calculation on history. This is unacceptable in backtesting strategies, but can be useful in indicators."

@capissimo I edited it to barmerge.lookahead_off. The strategy results drop to 30%.
Well done @capissimo and thank you so much!
I tried adding in an alert to test it but in vain. Nothing appeared as Normalized Vector Strategy after right clicking and selecting the alert option on chart.
Wonder if the alert coding works in version 4. Please help. Thanks!
@TY19, Everything works when you remove strategy keyword and all other startegy statements. Replace the header keyword with the study and voilà )
Frankly, I haven't digged into it so far.

@capissimo, I replaced it with study and commented some codes. The alert works now. Thanks!
@TY19, you are aware of the repainting?

@dpanday, Yes, as mentioned by @capissimo in the script, there is a repaint problem in this strategy(Refer line no.16) but I would like to test it how frequent it happens. Normally during testing I won't do any live trading. If there is improvement done to resolve the repaint in the futures, that would be great.
