What you can try in the Sandbox
Buy the Dip
Set aside cash and margin for 10%, 15% and 20% drops from a holding's 52-week high, then review each installment when a daily close crosses a level.
Build Cash Reserve
When prices run well above their 1-year average, save part of the monthly budget, then release it in stages during a dip.
Margin health
See how much the account could fall before a maintenance call, and stress-test it with a sudden market drop.
Returns at a glance
1 day to all-time returns and charts for each demo account, calculated from the same fictional history so the numbers line up.
