As all the above are variable (by the broker) and unpredictable … I would think that the Systems, Indicators and Screeners on here give just as reliable / unreliable results (due to above challenges) on exchange data as they do on CFD / SB data??

Results from code on here may even be more reliable on exchange data … due to less variation in the challenges listed in previous post?

For example … I’ve been getting attached error message all day on a System that has worked fine on the DJI for weeks up until today. I can’t see a Regulated Exchange playing the same game with their customers??

I may be talking myself into an exchange linked account here?? 🙂
