balance = 0.01 * 10 * 1,000
balance = 100
you need 100 per chart for StartLotQty=0.01
with 900, you will be safe with about 7 or 8 charts. If you are scalping, change StartLotQty to 0.03, it will default target to $0.03 (TakeProfit = StartLotQty * Contract_size / 1000) and reduce the quantity of charts to 4
if you increases StartLotQty then reduce quantity of charts.
I do prefer to have more charts, different symbols, instead of increasing the StartLotQty. it will diversify better.
Note that symmetry is been the more safest EG style, consider it.
