If I switch to another cfd broker dealing all day like IG, you get the same chart as in PRT (including same values for ATR). See screen capture. What this means with respect to signals given by this indicator with a opening hours only broker versus a 24-24 broker, I do not know. More, less, more or less reliable, … happy backtesting.
Yes !
This is what I thought of the very first thing this morning, but then I could not find the “logic” in how PRT would deal with IBKR and the choice there to work with RTH or ETH. So there I started to make coffee and think of other things.
Anyway, something would be wrong if we would be dependent on the view of looking at the market. With IG it would even be worse, because their ETH is “made up”.
Just my 2c. No opinions or anything.
