I'm looking for an indicator that will simply place a mark on a price bar at a certain point back in time. For instance, it would mark the bar that was 50 bars prior to the current one to give an immediate view of whether the current price is above or below where it was 50 bars ago. I've had a good search around but have only been using metatrader for a short while and haven't found anything to do this. I'd really appreciate it if anyone could point me in the right direction for finding something like this. Thanks.
