$9000 is 2%.
Personally i wouldnt risk $9000 when starting out.
I would start risking $500 per trade, and scale up to $9,000 eventually.
Be extra conservative with initial capital, but take more risks with profits.
Avoid going into a big hole with your initial capital.
Lets say i made 100K, so i was at 550K, i would obviously be betting more than $500 per trade at this point.
But if i fell back to $450K i would be back to betting $500 again.
For new traders, they recommend 1% of capital which is $4,500 per trade. Place a hard stop loss after entry too. Most times, you do not lose 2% (total loss), maybe, 0.5% or 1% tops. So, even after several losses, you are still A-Okay with most of your capital intact.
