P&L and the position numbers

Open, realized and net P&L, equity, average price, and what the position chip is telling you.

Avg priceThe average fill price of the open position, on its own price-axis tag.
Open P&LUnrealized: (last price − average) × units for a long, the reverse for a short. It moves with every tick.
RealizedP&L locked in by closed trades, after commission.
EquityStarting capital + realized + open P&L. What the account is worth right now.
MarkThe price the open P&L is valued at: the last price.
%P&L as a percentage of the entry value.
RP&L ÷ the money at risk to the initial stop. +2R made twice what was risked. Needs a stop at entry.
A worked long on NIFTY BANK (lot size 30)
Buy 2 lots @ 51,200.00   = 60 units
Last price    51,245.50
Open P&L      (51,245.50 - 51,200.00) x 60 = +2,730.00
Stop at       51,150.00  -> risk (50 x 60) = 3,000.00
R             2,730 / 3,000 = +0.91R

The position chip's P&L cell can read in money, points, ticks or percent (Settings → Trading → P&L display). Points are what index traders count; money is what the account feels.
