The issue is that when I draw a global trendline on, say, M5, then switch over to M1 and look at it, it is significantly inaccurate. This can happen regardless of whether I choose tightly spaced or widely spaced points for the two trendline anchor points.
Attached are two pictures of the same global trendline on M5 and M1 (it was drawn on M5), you can see the values are identical, however on M1 the trendline is very inaccurate (compared to M5, where it was drawn).
I've determined via experimentation that this is likely due to the instrument I'm using, as this issue does not happen on CL, but it does happen on NG (natural gas), and I suspect it may be due to the much smaller pricing of NG (in the $2-$3 range versus CL which is in the $60-$70 range). My guess is that the calculation of these trendlines is not accurate enough to properly display on low-priced instruments when they are drawn on higher timeframes initially.
If this is indeed what is occurring, is there any way to mitigate this? By the way, the exact same thing happens on NT8, I tested it.
