Immediate — never a market order: posts a limit at the book's best price (maker fee), re-pegs up to 3× if price moves, tiny capped taker only as last resort.
50/50 — half fills now; the engine watches: if price backs up ~1.5% it fills the rest at that better price, if it runs 0.6% without you it chases the rest in.
Limit — rests exactly where you say (tap a book level to prefill).
⚡ QuickScalp — one tap: book entry, then auto TP 0.75% + SL 2% land on the exchange the moment you're filled.
⚡ QS+Trail — same, but the stop follows price at 0.8% instead of sitting still.
Trailing stop — exchange-side stop that ratchets with every 0.1% move in your favor; survives even if this app dies.
Break-even at +1R — once profit equals your stop distance, the stop jumps to entry: the trade can no longer lose.
