It repaints.
I read your comment yesterday and thought about it overnight. Typically, I don't write too much in my replies, but I thought I would offer free advice to save you time as I was deep in this rabbit whole a few years ago with harmonic patterns. I recreated this script with Peak and Trough Analysis, which is somewhere in the platform, to back test harmonics. I ended up scraping that with a custom set of pivots they are profitable alone – meaning, many, many interactions for pivots. It took a year and half to make a harmonic trade strategy profitable, but harmonic trade management has too many variables. Here are the facts that I currently believe:
- Scott Carney stole his harmonic ideas from Bryce Gilmore. This can easily be verified by reading his material. If you are dead set on trading harmonics, read Bryce Gilmore. His 90% reversal rule is legitimate and most of his books are thorough and free. I keep an algo running to recognize his 90% reversal rule, and don’t trust my initial code if you find it. It is faulty.
- Don’t trade the big-name patterns such as Gartley. There are too many smart money computers identifying it so they reverse it all the time against dum money. A bat pattern doesn’t need ingenious trade mechanics as it is a very reliable pattern. My second is cypher. I know this as I back tested every time across the DOW.
- DOW symbols respond better to harmonic patterns for some reason. Research has been done to verify this.
- Most harmonics are like a double bottom/top pattern. Instead of coding or buying a harmonic pattern script, find a decent pivot code and draw lines from the high and low. Trade when price touches of those lines instead.
