What is "deposit load"?

 
I am following a MT4 signal but confused with "deposit load" labeled on the chart of tab "Risks". Can anyone explain its meaning? Thanks.
 
Is the percentage of capital that is used for margin during the opening of trades.
 

If the deposit loading ratio = reserved margin / equity = 10%

and financial leverage = 100:1,

then trading volume = financial leverage * deposit loading ratio”

trading volume = 100 * 10% = 10 times the equity in the account.
