Stopline is a multi-exchange execution and risk layer for crypto trading. Autonomous strategy Runners, an AI second-opinion gate, and one safety rail every order has to clear — whether a human, an AI, or a script placed it.
Most retail bots optimize for entries. Almost none treat risk management as infrastructure.
Crypto trades 24/7. A thesis can invalidate at 4am with nobody watching.
Most bots let a script skip the checks a human trade would go through — or skip them entirely.
Strategy logic wired directly to a single venue's API means starting over on every migration.
Set-and-forget bots grade the entry once and never look at the position again.
Whether a trade is manual, AI-advised, or fully autonomous, it earns its way onto the exchange the same way.
API keys stay scoped to your own account. Testnet or mainnet, your call. Stopline never takes custody.
Pick a sizing mode — fixed notional, % of equity, or ATR risk-based — plus correlation caps and allow/blocklists.
Symbol rules, correlation cap, funding/interest-rate policy, an optional AI second opinion, and a mandatory stop-loss — before anything reaches the exchange.
The invalidation monitor re-scores every open position and tightens stops as the thesis decays or reverses. It never loosens one.
One adapter interface per venue. Binance and Bitget are fully live today; the abstraction is what makes adding the next one an adapter, not a rewrite.
Configured strategy instances with three sizing modes — fixed notional, % equity, or ATR-based risk sizing — each capped by what the account can actually afford.
A manual click, an AI-advised entry, and a Runner all pass through the same route. None of them can open a position with no stop attached.
30-day return correlation checked before entry, so a position-count limit can't be quietly defeated by ten correlated altcoins that are really one leveraged bet.
Independently configurable gates on futures interest rate and funding rate — block, cap, or ignore, set directionally because funding sign matters.
An optional gate that has to agree with a trade's direction to let it through — and fails open, so a rate-limited provider never freezes the system.
Runs continuously against every open position. Reversal signals tighten aggressively toward breakeven; decaying conviction tightens gradually. Stops only ever get tighter.
Real-time price, PnL, and SL/TP aggregated across every exchange connection — one source of truth instead of reconciling tabs by hand.
Stopline places live orders against real matching engines. Every design decision treats risk controls as load-bearing, not optional middleware.
A few rules apply to every account, on every plan — they're not a toggle.
Early-access pricing — subject to change before general availability.
Get familiar with the signal engine before automating anything.
Full autonomy, for one account.
Multiple accounts, multiple exchanges, dedicated support.
Stopline's gate architecture — one route, one set of checks, full origin logging on every trade — is what a compliance-minded desk needs from automation, not something bolted on after the fact.
Concrete engineering choices, not a marketing claim.
Automated crypto trading is a crowded category. A version of it built with the same rigor as trading infrastructure — where risk controls are the product, not an afterthought — is not.

No. Stopline is independent software that connects to exchanges via API keys you provide. It is not affiliated with, endorsed by, or sponsored by Binance or any other exchange.
No. Your assets stay on your exchange account the entire time. API keys are scoped by you, at the exchange, and can be revoked at any time — Stopline never takes custody.
Binance and Bitget have full trading support today. Several other exchanges are represented in the schema and UI but not yet wired up for live trading — more adapters are on the roadmap.
The current deployment runs live against Binance and Bitget testnet. The architecture doesn't distinguish testnet from mainnet at the code level — rollout to mainnet accounts is a deliberate, gradual next step, not a rebuild.
Yes. Runners and the AI gate are both optional. You can run purely on manual trades or the live signal scanner and skip autonomous execution entirely.
The entry is rejected. Stopline will not open a position — of any kind, from any origin — without a stop-loss attached.
