Computed values (derived from this array):

• _tpClosed: Sum of all "profit" type partial close percentages
• _slClosed: Sum of all "loss" type partial close percentages
• _totalClosed: Sum of all partial close percentages (profit + loss)

• For SHORT: moves downward as price moves toward TP (never moves up) When _trailingPriceStopLoss is set, it replaces priceStopLoss for TP/SL checks. Original priceStopLoss is preserved in persistence but ignored during execution.

Copy

Trailing take-profit price that overrides priceTakeProfit when set. Created and managed by trailingTake() method for dynamic TP adjustment. Allows moving TP further from or closer to current price based on strategy. Updated by trailingTake() method based on position type and percentage distance.

• For LONG: can move upward (further) or downward (closer) from entry
• For SHORT: can move downward (further) or upward (closer) from entry When _trailingPriceTakeProfit is set, it replaces priceTakeProfit for TP/SL checks. Original priceTakeProfit is preserved in persistence but ignored during execution.
