TD Perfection Indicator for ThinkorSwim

I wrote this script after reading about the algorithm from a public website but added my own twist. It can be used for scalping.

Dots above and below the signal is the support and resistance levels.

Let me know what you think and how I can improve it.

# Buy Perfection

@HighBredCloud this is a study. It is possible to adopt to a strategy though. It doesn't repaint. With limited testing, I found it has good results with 2000t.
I added it as a study on a 15 min chart...I need to see how it reacts...Have you tested other time frames other than tick charts to see where this indicator works the best?

Forgot to mention, I use k=8 and i=13 for 2000t chart. I am not sure what parameters will work better for different time frames.

@tabs999 arrows indicate buy or sell. dots indicate support and resistance. you may want to set stop losses at support and take profit at or above the resistance.

@technicallydreaming It will repaint as it is coded right now. Backtesting is not accurate. You should take trades after the bar closes.

I am looking into having it based on one previous bar so it doesn't repaint, or use the open price instead of close. Not sure how the performance will be with open price.

If it doesn't change after the bar closes, then it doesn't repaint. Repainting means it changes AFTER the bar the signal is on closes. All indicators based on Close will not be solid until the bar finishes closing.
