Automatic position size based on desired account risk in %

With added features:
1) % calculated on Balance / SL as requested initially.

2) % calculated on Balance / TP.

3) Static % based on current Balance or Equity.

4) Reverse the function to use a static % of Balance or Equity which automatically sets SL/TP levels based on user input ratio. eg, 10% of Equity automatically sets 1:3 SL : TP (Equity = $100, Order Amount = $10, SL = -$10 / TP = $30).

Something like this would be even better:

Red area = unavailable funds

Yellow = the position you are allocating

Grey = total position.

I would vote for this provided it included the ability to set a fixed Risk amount in the Account Currency. E.g I want size my position according to the SL I set with a risk of USD100 regardless of available margin or account size. Actually I'm writing a custom indicator to do this, that's why I have posted the question about horizontal lines in C# on the forum :-)

Expanding on this great and very essential idea,

With such feature in place, the "order entry" menu, could then allow to execute the same position along "All" accounts with the same risk level (%). That would be awesome!
