Prop scalpers: copying signals into prop is a bad idea

[PropScalpDesk]

Copying someone else's entries into a prop account fails for boring reasons.

Their size, hold time, and news policy are not yours. A signal that works on a netted book can breach a daily loss limit in three tickets on a challenge. Latency between their fill and yours turns a scalp into a chase. And if the firm cares about EA or copy behaviour, you may be inventing a compliance problem on top of a trading one.

What I do instead if I want accountability: same watchlist as a peer, independent triggers, compare journals on Sunday. No mirrored tickets. If I cannot explain the entry in my own words before clicking, it does not go on the prop account.

Prop scalping is already constrained. Adding another person's timing is how you inherit their mistakes at your leverage.

If a signal channel is part of your learning, keep it on a read-only screen during challenge hours. Learning is allowed. Mirroring fills is not how I run prop risk. Peer review of journals is welcome. Peer control of the order ticket is not.

The latency point is the one people underestimate. If the signal provider gets filled at the level and you get the alert 20 seconds later, on EURUSD M1 that can be two or three pips worse. With a five pip stop, you've just changed the risk to reward completely without noticing.

I'd add another boring reason: the provider's losing streaks aren't your losing streaks in size terms. They might be risking 0.5% on an account with no daily limit. Four losers in a row is a normal Tuesday for them and the end of a challenge for you.

Where I partly disagree is on the read only screen. For some people, having the channel open at all during challenge hours is the problem, because the urge to copy is there every time a call goes off. I'd rather close it until the session is over and read the calls afterwards.

Comparing journals on Sunday with a peer is a better idea than most people realise. You see their reasoning, not just their entries.

Have you seen firms actually flag accounts for trades that match a public signal channel?

One case I'd like your view on, PropScalpDesk, is when a channel call lands on a level that's already on my own card. Independent triggers sounds clean until the provider posts a short at the exact high I marked at 07:30.

My rule is that I take my own entry, stop and size, never theirs, and tag the trade as overlapping in the journal. If the call came before my trigger, I still wait for my trigger, even if that means missing it.

The tag matters at review time. After a month I could see the overlapping trades did worse than my clean ones, mostly because I managed them with more confidence than they deserved.

That's the subtle version of the copying problem. Nobody is mirroring fills, but the call still leaks into the decision through conviction.

For anyone who wants to learn from a channel, I'd log every call for a month with the time you'd realistically see it. Then price the fill you'd have got at that moment with your normal stop, and a lot of the edge tends to disappear on paper.

Would you count an overlapping trade like that as a breach of your independence rule? I'm still not sure I should take them at all.
