Hello there, please help me.
Why are there shadows in range a chart's bars with the price range in 1 tick?
As I guess there shouldn't be any shadows in bars with 1 tick setting. Thank you.

there is no true 1 tick range bar, as price needs to move 1 tick to fill the body and then 1 more tick to create a new bar. That new bar has an artificial opening price that matches the last close but does not mirror what actually happened. But you can probably just change the candle type to something else like HiLo or sth (dunno, I am not on TOS) to make it look "prettier."
