The instant you enter a trade, NoVo attaches a protective stop — on Tradier a real broker-side order resting at the exchange, on Alpaca a stop enforced in NoVo's own software (Alpaca options have no broker-side stops). Understanding the difference — and its limits — is the point of this piece.
Why where the stop lives matters
There's a big difference between a stop that only exists in an app (which must be online, connected, and running to fire) and one that rests at the broker/exchange. On Tradier, NoVo places the stop at your broker, so it's live at the exchange independent of your device and of NoVo's own uptime — even if your laptop is closed or NoVo's server has an outage, the stop is still resting at the broker. On Alpaca the stop is software-enforced, so it depends on NoVo running — a full outage is a genuine gap there. That's real defense in depth where the broker allows it, and an honest limit where it doesn't.
How it fits the trade
The stop is attached automatically as part of one-click execution — you never have to remember to set it, and it's sized to the risk you defined. It works alongside the exit ladder (which scales out of winners) as the downside protection on every position. The point is that your risk cap is in the market from the moment you enter, not something you'll add in a second — discipline built into execution, resting where it's most robust.
On Tradier, a stop resting at the broker survives your laptop, your wifi, and even the tool that placed it. On Alpaca the stop is software-enforced — robust in normal conditions, but not outage-proof.
The honest limits
First, it only rests at the broker on Tradier — on Alpaca (no broker stops for options) NoVo enforces it in software, so a full NoVo outage can leave an Alpaca position unprotected until NoVo is back. Second, even a true broker-side stop is still a stop, not a shield: it executes at the next available price, so in a gap or fast move it can fill beyond your level (size for that). It protects the downside on the trade; it can't guarantee the exact exit price, and it can't prevent a loss — only cap the intended one. NoVo places the most robust kind of stop in the most robust place; the market still has the final say on the fill, and honest software says so.
