I have a couple suggestions that might help

One...cutting down posts to relevant information is appreciated around here....there is a crap ton of post most days...scrolling thru it is work...so re-reading a bunch of twice..three ...half a dozen times quoted reply(ies) gets old quick.

Second...many probably use phones with touch screens...and are able to resize charts to their preferred aspect ratio. So keeping one side of the thread relatively clear makes scrolling easier possibly.

Anything over say 1600x1900 is just too damn large.

Third...there are no rules on it as far as i know...so do as you like...but some common courtesy goes a long way.

Forth....it can be hard to pick up all these subtle little cues right off the bat...dont sweat it...participation is what is key.

Fifth...that diamond pattern is cool btw...nice of you to point it out...always give credit where credit is due tho.

ymmv...
