How PFArmour Works

Prop Firm Armour is a desktop software that you install on the PC you trade from — the same machine where your MetaTrader terminals (MT4 / MT5) run. Its job is to connect your prop firm account to a brokerage account of your own, so that the money you risk on prop firm challenges is covered while you trade.

The mechanism

You keep trading your prop firm account exactly the way you already do: your setup, your strategy, your decisions. While you trade, Armour automatically hedges your positions on your personal broker account.

The hedge is automatic and asymmetric: positions on the broker account are not opened with the same lot size as on the prop account, but with a different, variable lot size that Armour calculates from your cycle configuration. The asymmetry is the point — the goal is not to replicate your prop performance on the broker account, but to cover the monetary risk of failing the prop account.

In practice that means two exit scenarios for every cycle:

• If the prop account reaches its maximum drawdown limit (the challenge is lost), the hedge on the broker account is designed to return the challenge fee — and, depending on the cycle mode, a profit on top of it.
• If the prop account reaches a payout, the broker leg has absorbed part of the cost and the two accounts reconcile according to how you configured the cycle.

What you see while it runs

Armour runs locally on your machine and manages the MetaTrader terminals for you. Around it, the dashboard gives you the full picture of your operation:

• Cycles — the lifecycle of each prop account you arbitrate with Armour, with live connection status and projections.
• Erosion — a detailed breakdown of the friction costs your trading generates across both accounts.
• Accounting — what you have spent on challenges, what your broker accounts have produced, and what payouts have come in.

You can run several cycles in parallel, across multiple MT4 / MT5 terminals, each with its own configuration.

What PFArmour is not

Armour does not trade for you, does not suggest trades and does not touch your strategy. It is a risk engine that sits around your existing edge: the trading decisions stay entirely yours, and so does the responsibility for them.
