Personally I’m a Sierra Chart user and fan, but a lot of people (especially in the Forex space it seems) like to use MultiCharts as their trading platform of choice. So if that’s you, this is your chance to save a bundle on a software license!
NO CODE REQUIRED MultiCharts
They have a number of editions that include charting, backtesting, and even multi-broker automation (something I wish Sierra Chart had!)
This is a holiday sale so it will probably be gone in the new year. Grab it while it lasts!
