Does MT4 have this Tradingview feature?

Or is there a script one can download that will achieve the same result?  The ability to visually place a bracket order, view the r2r ratio, and have the order size automatically calculated based on the trade's risk amounts in USD and % account equity.

 
  1. Of course, it does. Chart → right click at a price → trading → choose.

  2. Search for a GUI/Trade Assistant EA (like mine for MT4): 'Money Manager Graphic Tool' indicator by 'takycard' - Risk Management - Articles, Library comments - MQL5 programming forum - Page 6 #55 (2018) and modified for screen resolution #75 (2020.02.17)
