A position is a single open entry on your broker account. Direction (long or short), size in lots, entry price, stops and targets if they were attached, and a floating result that updates every time price moves.
While the position is open, the result is provisional. The floating gain or loss has not changed your balance. It sits in the equity readout, real, but not yet realized. The moment the position closes, the floating number rolls into the closed balance and the entry disappears from the open list.
Accounts can hold many positions at once: different instruments, different directions, different sizes, all running in parallel. The total floating P&L of every open position is the difference between equity and balance. Subtract one from the other and you have a live read on what is currently exposed in the market.
Algorithms typically run one to a few positions per instrument at a time, with explicit rules for stacking, hedging, or rolling. Javlot publishes both the open positions and the closed-position history live on every strategy page. The broker truth is always a click away. If a strategy is sitting on three open positions right now, the page says three. Nothing buffered, nothing delayed.
