The collateral side adds up to what the Trove holds: ETH deposited, plus redistribution gains from liquidated Troves, less what was withdrawn, taken by redemptions and liquidated (and the surplus left to claim where a Recovery Mode liquidation or a redemption that cancelled the last of the debt closed the Trove). Each flow is valued at Liquity's ETH price at its block, so the last line, Market move, is the change in ETH's price since each flow.

The debt side adds up to what the Trove owes, in LUSD at its $1 face: borrowed, plus the borrowing fees, the 200 LUSD liquidation reserve the open adds and any debt redistributed from liquidated Troves, less what was repaid, redeemed and liquidated. Liquity V1 charges no interest, so between events the debt stays as its last event left it. The reserve is burned when the owner closes the Trove or a redemption cancels the last of its debt (Reserve burned); a liquidation pays it to the liquidator, so there it is part of the debt liquidated. The fee of one draw was not read from its transaction, so it stays in Borrowed.

A redistribution has no event of its own: a liquidation the Stability Pool cannot cover shares its debt and ETH out to the open Troves, and each Trove takes its share at its next transaction, which records the gains before its own change. That step is put on Redistribution gains and Redistributed debt at that event. None reached this life.

ETH is valued at the price Liquity's price feed held at each event's block: recorded with each redemption and liquidation, and read from the transaction for the owner's own events. One event takes the nearest recorded price before it. Between events the line and the bars keep the price of the Trove's latest event, a price more than 30 days old stated as such.

The bars and the sums cover this life of the Trove. A liquidated or closed life's slider stops the day after its last event.
