 # TheLark: Directional Movement Index Stochastic

7799 görüntülenme
There is a nice writeup about a system that uses DMISTO here, which includes decent statistics:

I have not yet done any back testing on the system as a whole myself, but thought the DMISTO was an interesting indicator, so ported it over for those who might want to play with it and create their own systems. I added dots that denote signals similar to the system described above, which can be turned off if desired.

## Yorumlar Oops forgot to switch to the weekly chart before posting. The link above is a system built for weekly bars. (But that really shouldn't matter on any decent system). Anyone looking to trade a system should be doing proper back and forward testing to help find ideal values without overfitting
Cevap Gönder Super interesting, love the article! How does this differ from the stoch?
