Market
A Market order fills immediately at the current price. Use it when you want in — or out — right now, no waiting on a fill.Limit
A Limit order rests at the price you set until it’s filled or you cancel it. Each order is placed with a long default lifetime (about a year), so in practice it sits until you fill or cancel it, rather than expiring on you mid-competition.Take Profit / Stop Loss (TP/SL)
Attach a take-profit, a stop-loss, or both when you open a position — or add and edit them later on a position you already hold. Set each trigger one of two ways:- By ROI %
- By price
The trigger fires once your position’s ROI hits the percentage you set.
Reduce Only
Reduce Only is a flag you attach to an order, not a separate order type on its own. It guarantees the order can only reduce or close your existing position — it will never flip your position or add to it.Partial closes
You’re never forced into an all-or-nothing exit. Close any percentage of a position — bank some profit and let the rest ride, or trim risk without closing out completely.Advanced order types — scale orders, TWAP, stop-market, and trailing stops — aren’t offered today.
