Swap Cost Monitor
Swap is easy to ignore because it never shows up as a single dramatic loss - it erodes a position a few cents or points at a time, night after night, until a trade that looks profitable on price alone is barely break-even once carry is counted. This tool scans every open position on a timer, sums swap per ticket and per symbol, and raises an alert either when one position's absolute swap passes a configured money threshold, or when swap has eaten past a configured share of that position's own price profit. Swap is compared only against price profit, never against commission. Commission is a one-off cost paid at entry; swap keeps compounding for as long as the position stays open. Blending the two into one ratio would flatten out exactly the growing-cost trend this tool exists to surface, so the two are kept separate on purpose. Alerts are rate-limited per ticket so a position that stays in breach does not spam a popup every scan; a repeat alert for the same ticket waits for the configured cooldown before firing again. Notes and limitations - The profit-share check only fires while price profit is positive; a position that is already losing on price is not additionally flagged for swap eating a profit that does not exist. - Up to 200 distinct tickets have their alert cooldown tracked at once; beyond that the oldest tracked slots are recycled, which could allow an early repeat alert on an account holding an unusually large number of simultaneous positions. - Read-only. It never sends, modifies or closes an order - only Alert and Comment are used to surface what it finds.
