Prop firm rules, enforced in software
PitBridge holds an AI agent to the risk limits you configure for a prop account. It is a software control that refuses orders which break your numbers. It is not a promise about your account, and it is not a substitute for reading your firm's rules.
What the software actually does
A prop evaluation is a set of constraints: do not lose more than X in a day, do not hold more than Y contracts, trade only these products in these hours. Some of those constraints reduce cleanly to a check at order time. Those are the ones PitBridge can hold for you. It watches each order the agent proposes and refuses the ones that break a limit you set, before the order reaches NinjaTrader 8.
What it does not do
It does not certify anything. No prop firm has reviewed or endorsed PitBridge, and running it does not make your automation acceptable to any firm. It cannot see rules that live only in your firm's back office, and it makes no claim that you will keep an account or clear an evaluation. It enforces your numbers. Your numbers being right, and your firm allowing automation at all, are yours to confirm.
How prop constraints map to guardrails
The mapping is deliberately literal. You translate your firm's rule into a value, and the named guardrail enforces it.
| prop rule | guardrail | what it does |
|---|---|---|
| daily loss cap | daily_loss_halt | Halts new orders once the day ledger reaches your number. |
| max position size | max_position | Refuses any order that would push net position past your cap. |
| allowed products | instruments | Refuses instruments outside the allowlist you set. |
| session hours | trading_window | Refuses orders outside your window and on calendar holidays. |
| order pace | max_orders | Refuses bursts past your per-minute, hour and day caps. |
| live confirmation | human_confirm | Holds a live order for your explicit approval. |
Live accounts get a second gate
Sim is the default. Moving an account to live is a deliberate command line step, and you can require explicit confirmation on live orders so nothing goes out untouched. An AI agent cannot arm a live account and cannot approve its own live order. Both are off the agent surface by design.
PitBridge may earn a commission when it links to a prop firm. No such links are live yet. When they are, any ranking of firms stays merit-based, the relationship is disclosed on the page, and we do not recommend an automation-hostile firm for a commission.
Questions
Does PitBridge make my trading acceptable to a prop firm?
No. No firm certifies PitBridge, and running it does not make your trading acceptable to any firm. PitBridge enforces the numeric limits you enter. Whether those match your firm's current rules is on you to check.
Will PitBridge keep me from breaking a prop rule?
It refuses orders that break the limits you configure. If you set the values correctly and your firm has not changed its rules, that helps you stay inside them. It is a software control, not a promise about your account status.
Which prop rules can it map to?
The ones that reduce to order-time checks: a daily loss limit, a maximum position, allowed instruments, session hours, and order rate. Rules that depend on end-of-day balance history or a firm's own dashboards live with your firm, not in the bridge.
Do you recommend specific prop firms?
Not yet. When PitBridge lists firms, ranking stays merit-based and we disclose any affiliate relationship. We will not rank an automation-hostile firm higher for a commission.
Can the AI agent turn a rule off to get an order through?
No. Limits load from a config file the agent cannot read or write, and arming a live account is a command line ritual, never an agent tool. See the guardrails pillar.
