What does the Equity represent?
The Equity represents the state of your account if you were to close all of your open positions and thereby realize your current gains or losses.
Therefore it is the sum of your Available balance (funds available to open new trades) + Total Allocated (funds currently invested in manual trades, other traders or Smart Portfolios, or pending orders) + Profit (the current sum of your gains and losses from all open trades).
