This is caused by the HighestAll() function used in HighestAll(bar) and HighestAll(cLine) in the dynamic function, but I for the life of me haven't found a work around to change the plot to use the latest candle values and paint the line across the whole chart.

I called TOS today and they said the {highestbar} was the issue as they changed this last weekend on the backend and they really didnt know how to fix it so it tracks the bid / ask tick for tick... If your ever able to figure it out and update the code that would be great... Thanks

# End CodeHi, I am definitely getting the syntax wrong. I just want to add study to filter in the scan screen, basically if the current (anytime including pre and post market) ask is greater than the bid, by let's say 5 cents, then it wouldn't show in the scan.
Is there a way to modify this to have it display a short line at the right side axis on the daily chart? Thanks@DojiDude Try this:

To my knowledge, custom scans don't work for options in TOS.
Thanks MerryDay! I just don't know how to plot the bid/ask over time. This indicator shows only the current bid/ask. I was thinking about making it a dot (rather than a line) and plotting it on the chart. I assume it has something to do with the dynamic function(?), but I wasn't sure after looking at the code.
Hi. I'm new to this site and TOS. I'm in search of a label that just displays the Bid/Ask Volumes. e.g. "154/299". I thought this would be a no-brainer. but can not find it. thanks
You replied to me, but that's not my code in your image as mine only shows the spread. I added an image to my original post and updated the code with an optional alert if the spread is wide.This is great, but there is small thing needed to be fixed. Sometime the code is having trouble reading ASK price from the source, BID usually works. anyway, it's causing this.
