Vervoort Heiken-Ashi LongTerm Candlestick Oscillator [LazyBear]

24373 visualizzazioni
HACOLT (Heikin Ashi Candles Oscillator Long Term) is a technical indicator designed by Sylvain Vervoort. It is based on Mr.Vervoort's other indicator, HACO (Heikin-Ashi Candles Oscillator - posted here:

Optimized for long-term trading, HACOLT shows three levels: -1, 0 and 1. These levels suggest "an open short position", "no open position", and "an open long position", respectively. Passing from a certain level to another is viewed as a trading signal:
- Rising from -1 or 0 to 1 suggests a Long Entry and Short exit;
- Falling from 1 to 0 or -1 suggests a Long Exit;
- Falling from 1 or 0 to -1 indicates a Short Entry.

Fits in nicely with any trading setup as a confirmation indicator

Hi Chris,
I tried to copy your code into a strategy code version 3 but have undeclared identifier error for HaOpen, HaClose, upwWithOffset and neturalSig.
I have tried to use the following and managed to solve it for HaOpen, HaClose and neutralSig. However, I am still getting propble with upwWithOffset stating it is bool series.
HaOpen = 0.0
HaOpen := (your definition)
If it is not too much trouble, can you advise how to change your code so that it can use with version 3?

Awesome. It's definitely both a interesting and a lagging indicator. Showing signals where most other indicators show something else:

3 different always opposing signals :)

The so called lag is actually good, makes you buy on a pullback if you're smart.
ChartArt IvanLabrie
It's not that every example looked as good as these obvious pullback chances.

I see you are still on your quest for that holy-grail setup. :)

Oh, yes. I am. And with each new indicator which I'm testing and comparing to others I'm coming closer to my goal :P That's one small step for (a) man; one giant leap for 'that holy-grail setup' :)
