Hi again Foreverold, the problem is that on the DJI, the little bright horizontal lines do not appear on the red and green verticals. I initially thought that this might be because it was designed for Forex, and invariably Forex pairs have a decimal after the first digit, which the majority of indices don't. However, it can't be this, because the YM looks like it has the same number of digits as the DJI. I don't recognise the YM, which index is that? I've checked several other indices also, and all the same. I can't see how the indicator could possibly know it was looking at a forex instrument as opposed to an index.
