Scale out — you will not catch the top
Selling in tranches banks profit and removes the all-or-nothing bet on a perfect exit. Set the ladder before you are emotional. Plan the downside too on the stop-loss calculator.
Placing the exit before the entry
A take-profit order pre-commits your exit. The calculator's job: turn "I want +$300 on this trade" into the exact price to set, after fees. For a long, TP price = entry × (1 + target ROE / leverage + fee adjustment). At 10x targeting 30% ROE from $2.00, that's $2.062 — closer than most people place it by feel.
The fee adjustment matters at leverage: a 0.055% taker fee on exit is 0.55% of margin at 10x. Set your TP at the naive price and you'll net less than planned on every single trade — small, systematic, entirely avoidable.
Whether to use fixed TPs at all depends on style. Data from scalp systems consistently shows TP-hit exits outperforming discretionary "let it run" exits — the average discretionary hold gives back most of the peak. Trend systems show the opposite. Know which game you're playing before deciding whether the TP is a discipline tool or a profit cap.
