At the current prices, Black longsword is not profitable to instant flip. If you hold this item, consider selling gradually via limit orders above the instant sell price rather than accepting the current spread loss.

Black longsword sells for a mere 279 gp on the Grand Exchange, so profit here comes from flipping in bulk rather than large per-item margins. The buy-sell spread is 24 gp (8.6%), which indicates a wide gap between instant buy and sell — typical of less liquid items.

Black longsword currently has a negative margin of -29 gp after tax, meaning instant flips would result in a loss at these prices. Margins fluctuate throughout the day — check back later or set a price alert to be notified when the margin turns positive. The price has dropped 4.8% in the last hour, which could signal a buying opportunity if the margin improves.

Black longsword barely moves on the GE with 11 recent trades, so buy-sell gaps tend to be wide and unpredictable. The buy limit of 125 every 4 hours is worth planning around when scaling flips.

A 8.6% buy-sell spread on Black longsword means patient traders can capture meaningful margins, though the tradeoff is slower fills and less predictable volumes. The price has dropped sharply — down 4.8% in the last hour. This could signal a sell-off or increased supply; it may be worth waiting for the price to stabilise before entering a flip.
