Roundup: Prop consistency rules and the lumpy reality of scalping
Consistency rules come up in five separate threads on the prop board, and they're worth reading together because each one catches a different way the rule bites. Here's the combined version, including where people still disagree.
What the rule usually says
The best-day thread explains the common form: no single day can be more than a set share of the cycle's profit, typically 30 to 50 percent. With a 40 percent rule and 5,000 total profit, your best day can't exceed 2,000. Make 3,000 on a Monday and you either keep trading until total profit reaches 7,500, or the payout waits. That arithmetic is the whole problem in one example, and a reply in the advanced notes thread says the most common failure is people only doing that maths after the big day.
Why it fights scalping
The "rules that punish real scalpers" thread lays out the conflict plainly. Scalping produces lumpy days. Some London opens pay, plenty are spread and noise. Consistency rules want smooth equity. A line from that thread, quoted back by a couple of replies, sums it up: lumpy expectancy and smooth equity curves are different goals. The rule doesn't care that your big day was a legitimate, well-executed day. It only sees the ratio.
The same thread flags two related traps. Minimum trading day rules can push you into junk trades just to paint the calendar. And daily loss limits sized for smooth equity can turn normal M1 variance into breach risk if you size like you would on your own account.
What people do about it
The split is between "trade normally and dilute afterwards" and "cap the day so you never need to". Diluting means keeping on trading after a big day to bring the ratio down, which one thread called pressure to trade when you otherwise wouldn't. Capping means leaving money on good days. Neither is free. My read is that capping fits scalpers better, because diluting tends to happen in exactly the conditions where you'd normally stop, but people who trade fewer, bigger days may see it differently.
The other caveat, repeated in every one of these threads: firms word this differently and change it. Check your own terms rather than anyone's summary, including this one.
For those who've been caught by a best-day rule, did you dilute or cap afterwards, and which would you do next time?

What people do about it
- A soft daily cap. Once the day reaches a share of the target that would break the rule, stop. The best-day thread suggests setting this from the rule itself, before the session.
- Scaling out carefully. The scaling-out thread found the problem wasn't scaling out itself but a good day with a runner pushing that day over the line. The fix was taking the runner off earlier on days already near the cap.
- Reading the fine print twice. The advanced notes thread lists what to check: whether the cap is soft or hard, whether lot size consistency is expected on top of profit consistency, and how news bans interact with it.
- Screenshotting the rules page with the date visible, because rules change and support will point you at the current version.
