Expose Bookmap TCP data to the API

[luis]

It will be extremely helpful for Trading Strategies addons if the Bookmap TCP (Trade Control Panel) values can be exposed on the API (Simplified or Core). This way the addons can use a central location for order size, brackets (TP/SL) and trail settings.

This would be highly appreciated as all addons could use the Bookmap TCP values and users could just set the order size/bracket settings there and that would be available on the API if you have an addon that does implement trading strategies.
