HOW-TO: Read the real break-even line with Cost CompassBitcoin / TetherUS PERPETUAL CONTRACTBINANCE:BTCUSDT.PloweefThis is a how-to for Cost Compass : What the chart shows: a BTCUSDT perpetual on the 15-minute timeframe with the default inputs (long, 1,000 USDT margin at 10x = 10,000 USDT notional, taker entry and taker exit at 0.05%, 24 hours of holding with the average funding of four exchanges). STEP 1 - Set your position Open the settings and enter your side, entry price (0 uses the last close), margin and leverage, and the holding time you expect. Enter your own maker and taker rates from your exchange's fee page; the script does not assume any exchange. STEP 2 - Read the three lines - Grey line: your entry. - Amber line: the real break-even. In this example it sits about 0.12% above the entry, because 10 USDT of round-trip fees and about 2.4 USDT of funding have to be paid back first. - Red dotted line (bottom of the chart): the approximate liquidation price (flat maintenance margin rate input, so treat it as a rough reference). STEP 3 - Read the distance in ATR The dashboard shows the break-even distance as a multiple of ATR. On the daily chart the same position needs only about 0.05 ATR to reach break-even; on this 15-minute chart it needs about 0.65 ATR. The cost is the same in dollars, but much heavier relative to how far price normally moves on a short timeframe. This is the main thing to check before scalping. STEP 4 - Compare a lower fee level The teal dashed line shows where break-even would be if both fee rates were 30% lower (the percentage is an input). Use it to see how much your fee level matters for your style of trading. STEP 5 - Funding source Auto averages the funding rate of Binance, Bybit, OKX and Bitget for the chart's base asset. Switch to Manual to type a rate, or Off to see fees only. If you hold a long while funding is negative, the funding row turns into income and the break-even moves closer. Limits: slippage and spread are not included, funding changes every settlement, and the liquidation line ignores tiered maintenance margin. This is an educational example, not a trade idea or a signal.
