Equity

Balance plus or minus your current floating P&L — what you'd have if you closed every trade right now.

Equity is your account balance combined with the unrealized (open) P&L of every active trade. Unlike balance, equity moves in real time. Every pip your trades move in your favor, equity ticks up. Every pip against, it drops. Equity is the number that matters for margin calls. When equity falls below a certain threshold (usually 50% or 20% of used margin depending on the broker), the broker starts auto-closing positions. That's why traders who over-leverage can get wiped out overnight even though their balance "looked healthy." If you have zero open trades, equity = balance. The moment you open a trade, they diverge.
Real trade example

The 2015 CHF shock destroyed thousands of retail accounts — equity went from positive to negative in seconds as stops gapped through. Many brokers had to forgive the negative balances just to survive.
