Many futures prop firms judge you on more than total profit. Under a consistency rule, your single best day cannot make up too large a share of your total profit — and if it does, a payout request can wait until the balance of your days catches up. The arithmetic is simple but tedious to redo by hand after every session, and easy to get wrong when you are tired. RuleGuard, from Mergify Digital, is the checker built for exactly that moment: enter your daily P&L, set your firm's best-day cap percentage, and it checks whether your biggest day stays within the rule — and shows how much more total profit you need so that it does.
A consistency rule caps how big your best day can be relative to your total profit. If your firm sets the cap at a given percentage, your largest winning day has to stay at or under that share of everything you have made. One outsized day — the kind of day that feels like a breakthrough — can push your best day over the cap even while your total keeps growing, because the cap is a ratio, not a fixed dollar amount. That is why the check has to be re-run as your figures change: every new day moves both the best day and the total, and the answer you got last week may not be the answer today. RuleGuard's product page puts its job plainly: it does this arithmetic for you before you request a payout, instead of leaving you to discover the rule at the payout desk.
The tool performs three named jobs. First, the daily P&L check: you enter your daily results and it checks the series against the rule. Second, the configurable best-day cap: you set the cap percentage to match your own firm's consistency percentage, because firms set different percentages and the checker has to work with your firm's number, not a generic one. Third, the profit-needed figure: when your best day is over the cap, RuleGuard shows how much more total profit you need to bring that best day back within it. The homepage's own worked example shows the shape of the answer — a best day flagged over cap, and a specific dollar figure for how much more total profit that day needs around it to stay inside the rule. That figure is the practical output: it turns "am I compliant?" into a concrete target for the trading ahead.
The product page lays out four steps. One: buy on Whop — checkout is a one-time purchase handled by Whop. Two: open the tool through the access delivered in your Whop account, with the included instruction guide, which covers entry and cap setup with every purchase. Three, on first use: set your firm's best-day cap percentage, then enter your daily P&L figures. Four, in everyday use: update your daily figures as you trade and re-check before assuming you are within the rule. That last step is the habit the tool is built around — the check takes the figures you already have, and it is meant to be re-run as those figures change, not consulted once and forgotten.
The product page names its audience directly: futures prop-firm traders trading under a consistency rule — Apex, Topstep, FTMO-style rules and similar — who want the arithmetic done for them before requesting a payout. RuleGuard is $19, a one-time price. Like every Mergify Digital purchase, it is delivered securely via Whop with an instruction guide included, and the homepage offers the choice the whole catalog offers: buy a single tool once, subscribe, or get the whole toolkit in the OmniSaaS Suite.
RuleGuard is a calculator, not financial advice — its own disclaimer says so. It performs arithmetic on figures you enter against a percentage you set; it does not verify your firm's current rule, and it does not guarantee any payout. Payout decisions are made solely by your prop firm under its own rules, and firms can change those rules. Trading involves substantial risk of loss. Use the checker to keep your own arithmetic honest and current, and confirm your firm's current consistency terms with the firm itself before you rely on them.
It is a rule that caps how large a share of your total profit your single best day can be. If your best day exceeds the firm's cap percentage of your total, you may need more total profit — spread across other days — before that best day sits within the rule.
You enter your daily P&L and set your firm's best-day cap percentage. RuleGuard checks whether your biggest day stays within the rule and shows how much more total profit you need so that it does.
The cap is configurable — you set it to match your firm's consistency percentage. The page names Apex, Topstep, FTMO-style rules and similar as the audience. RuleGuard does not verify your firm's current rule; you enter the percentage.
$19, one-time. Checkout is handled by Whop, access is delivered through your Whop account, and an instruction guide — entry and cap setup — is included with the purchase.
No. It is a calculator that performs arithmetic on the figures and percentage you enter. Payout decisions are made solely by your prop firm under its own rules, and the product page's disclaimer states this plainly.
