I'd like to humbly suggest adding some summary metrics and trade-specific data fields to the Live Trades page. This would enhance the Trade management and Trading activity.
I followed the existing OO's design and created HTML mockups to demonstrate these ideas (pic #1).
Not to overload the backend engine, these metrics can be updated just once per minute, for example, 5-10 seconds after the minute starts.
  1. Add the Trades Summary metrics for all opened Trades:
- Total Accounts Balance | Total Buying Power (from the broker);
- ROC (Return on Total Accounts Balance) | ROBP (Return on Buying Power);
- Net Positions Opened (negative = debit paid | positive = credit received);
- Debit Opened | Credit Opened
- Positions Net Liquidity;
- Debit Pos Liq | Credit Pos Liq;
- Open Greeks (sum of Greeks for each open trade).
These metrics would eliminate the need to manually calculate total exposure and P&L across multiple positions, saving time during active trading sessions.
  1. Add additional fields for Cards/Table view for each Trade (see pic #5 - red squares):
- Account (in what account the trade is opened);
- Days in Trade;
- Current Greeks (would help quickly assess trade risk exposure);
- Exit filed (Profit Target | Stop Loss | Delta exit | Timed exit etc).
* Trades Summary could be made per account (pic #2) and with the button of Private view to hide all metrics (pic #3).
* The Table view just repositions the Card view (pic #4)
I'm not a specialist in programming, coding and web-design, but eager to help if needed =)
All numbers are hypothetical. I can't attach the html-files to this post - they might give a better perspective - but I'm happy to share them.
