I am not able to find all variables under 'Margin' section earlier in the new version.
In the latest update (v.5.17.11 and above) we have grouped all of the different variables under 'Funds', 'Eligible Holdings' and 'Used Margin' sections.
We have done this to make margin calculations more accessible and easier to consume for our user.
Under each section, users can find a bifurcation and explanation of the variables.
