Charting spreads in Thinkorswim

[ex3y7s 149]

I know this has been covered before but the search and my search-fu leaves a lot to be desired. What's the magic to chart the midpoint of an options spread in TOS? I've added the symbol to a chart with what I believe to be the correct syntax, for example this PLTR straddle:

 

.PLTR241108C41.5+.PLTR241108P41.5

 

The chart shows the mid and the bid/ask at the top in the data section, but doesn't actually display a chart: it just keeps spinning "Waiting for data...". Do I need to tweak a setting or does this functionality no longer work on TOS, or perhaps only work for certain spreads?

ToS won't plot anything if there are no trades for any of the specified legs.So it's actually waiting for data to happen.

Thanks for the fast reply, and good to know! I thought perhaps there was a setting to chart the calculated mid like in IBKR.

I had added it to the wishlist for ToS a while ago. I guess they figure it's not important enough for it to be on their immediate radar.
