a stop-loss is an order that closes your position automatically when price moves against you to a level you defined in advance. a take-profit is its mirror: an order that closes your position automatically when price hits a level you set on the winning side. both are pre-committed exit instructions. they save you from yourself in the two situations where humans are worst: panicking on losses and getting greedy on wins.
in plain english
stop-loss is "if it goes this bad, get me out." take-profit is "if it goes this good, lock it in." you set both before the trade starts, and the protocol pulls the trigger so you do not have to. they are the cheapest, simplest discipline tool in trading.
why both exist
the two orders solve opposite emotional failures:
- stop-loss prevents catastrophic loss when a trade goes wrong and your brain says "it will come back."
- take-profit prevents giving back gains when a trade goes right and your brain says "what if it doubles."
- together they define a fixed risk-reward envelope before the trade begins.
- they let you walk away from a position and have it close itself at your chosen exits.
how stop-loss and take-profit trigger
most venues use last price or mark price as the trigger reference. when the chosen reference crosses your set level, a market order fires to close the position. that close order is itself subject to slippage, so your real fill can be slightly worse than the trigger price. on volatile pairs, this slippage matters.
how it shows up on uponly.win
uponly is intentionally minimal: tap rip, hold, tap close. the avantis routing under the hood does support tp/sl, and that functionality may surface in future versions of the uponly ui. for now, the most reliable risk control on uponly is position size: rip an amount you are happy to lose entirely, and the absence of a stop-loss becomes irrelevant. for the philosophy on sizing at high leverage, see max leverage trading 101.
common confusions
stop-loss and take-profit can both be set on the same position simultaneously; you do not pick one or the other. they are also not free in expected value: in choppy markets, stops get hit by noise and take-profits get jumped over by gaps. but those costs are usually less than the cost of holding through a real adverse move with no exit plan.
- stop-loss closes on adverse move, take-profit closes on favorable move.
- both can be active on the same position at the same time.
- trigger price is not the same as fill price; slippage applies.
- they reduce risk but do not eliminate it: gaps can jump through stops.

on uponly, the closest thing to a stop-loss is sizing your collateral so a full loss is acceptable. open uponly, pick a size that would not ruin your day, and tap rip.
