GFT forex does offer this on their platform, which I by the way consider to be as good as the one CMS offer; except.... that the vertical adjustment option of the price chart is pi...ng me off some times.
And on that point the CMS platform is superior.
On the other hand if you ask me which broker I would trunst with my money CMS would not be on the top half of my list. (No need to comment on this since it is only my personal feeling)
