50 usd is really too low. Below is the calculation:

Say you wanna open 0.01 lot with 1:20 leverage, you'll need a balance of :
$100,000 x 0.01 / 20 = $50 required as margin. So that leaves you with $0 in your account, ngam ngam margin call.
You should at least put in $500 and risk 2-5% of your account rather than blowing out your account, risking >50% of your account on a single trade.

told u minimum <100usd tak perlu fikir test live...
