Two separate sets of rules apply to a prop firm account. It helps to keep them apart.
Your firm's rules
Your firm sets these and your firm enforces them: the daily loss limit, the drawdown line, the profit target, the consistency rule, and how many contracts the account may hold. Break one and your firm can close the account, whatever Wildflower shows.
Wildflower shows these rules with where they came from, and measures your account against them. It acts on one of them, described below.
You enter them once, on each account's Your firm's rules page. If you run several accounts on the same program, that page can copy another account's saved rules into this one. You then check the fields and save them as your own.
Your own limits
You set these and Wildflower enforces them: your risk per trade, your daily loss and daily profit stops, how many losses in a row end the day, your trading hours, your rest window and your news window.
They are yours to set and yours to change.
The one firm rule Wildflower acts on
Your firm's maximum-loss line is the balance at which the account fails. Before every entry on a prop account, Wildflower works out the room between your balance and that line, after anything already at risk in open positions. The line comes from your account's setup and your firm's researched rules, including a line that follows your highest balance. If your firm measures that line at the end of each day, it follows your highest closing balance, not a brief high during the day.
A trade may not lose more than that room. What one contract can lose is its stop, plus a four-tick allowance for a worse fill, plus fees. If your size would lose more, it is reduced to what fits. If not even one contract fits, the trade is skipped, and your activity feed says why.
The line is taken from your account's setup: your starting balance and the balance the firm fails the account at. If the setup gives no line at all, prop trades are skipped until it is filled in, rather than placed without the check.
This never makes a trade bigger, and it applies only to prop accounts, never to practice accounts. Backtests of the account use the same rule on their own running balance.
What Wildflower will not do
It will not tell you what your firm allows, and it will not switch a feature off because of which firm you use. Wildflower shows the rule and where it came from, shows where your account stands against it, and you decide.
If a rule has not been researched for your firm, the meter says so instead of borrowing a number from another firm. Check your firm's own rules page.
What can go wrong
Firm rules change. The account page shows how long ago the rules were checked, and flags them once they are old.
