Price is not random, but time is. That invalidates all back testing (curve fitting) on time based indicators.
There’s 1440 minutes every day, day after day. Nothing random about that.

Post-hoc, not dynamic, but I'm not gonna argue the topic except in personi will agree back-testing is misused and not for most people, but statistics are just facts laid out before you.
I don't understand, you just said no indicators. Price action is an indicator, just trying to clarify if can use indicators or not.
Well,.. according to your definition it falls in the class of indicators. I see your point and most would consider bars or candles as the movement of price over a span of time. They are not like a RSI, MACD, etc which uses the movement of price as an input.
I’ve traded with tables so I do understand what you are describing in price charts as an “indicator.”
Scat, your charts are totally naked- no volume bars in another frame- no moving average or similar?
The context here is trading. Of course seconds do not occur randomly. Does that even need to be stated? Lets look at it in a different way. When the next tick will occur is unknown and so can be treated as a random event. It is very important to understand that the future rate of change is unknowable. Back testing will arrive at some sort of average, but that is not very helpful, all it will do is lengthen the time taken to empty your account.There’s 1440 minutes every day, day after day.
