How to check if a trader is legit before you pay for their calls

The short answer: don’t pay for anyone’s calls until you’ve seen a record read from their real account, with every call timestamped before the move and every loss still there. Screenshots, win-rate claims and testimonials can all be made up. A connected account can’t.

Paid trading groups, signal channels and “mentors” sell one thing: the belief that following them will make you money. Most of them show you only what they want you to see. These five checks cut through it.

1. Is the record read from a real account?

Ask where the numbers come from. A legitimate record is read directly from the trader’s broker or exchange through a read-only connection, so the trader can’t type in their own results. If all you get is a screenshot, a spreadsheet or a PDF, you have no proof at all: any of them can be edited in a minute, and a screenshot can come from a demo account or the one good account out of ten.

2. Were the calls posted before the move?

“I called this” after a stock has run is worth nothing. What matters is a call recorded with a timestamp before the price moved, that can’t be changed afterwards. The strongest version is a call sealed with a cryptographic fingerprint, so anyone can check later that not a word was altered. How sealed calls work.

3. Are the losing calls still there?

Every trader loses. A record with no losses has been cleaned. Check that calls can’t be deleted or quietly edited, and that the bad ones stay on the profile next to the good ones. A trader who is right 55% of the time with disciplined losses can be worth far more than one who shows ten winners and hides twenty losers.

4. Is profit measured on closed trades?

Open positions can look great on paper and vanish the next day. Realised profit and loss, worked out on trades that were actually closed, is the figure that tells you whether a trader banks gains. Be wary of a portfolio value on its own: it rises with deposits as easily as with good trades.

5. Is their own money really in the market?

Someone selling calls should be trading them. A verified balance read from their account shows they have real money at stake, and how much. It doesn’t make them right, but it rules out the people who trade nothing and sell everything.

Red flags

• Guaranteed returns, or monthly gains that sound too good to be true.
• Results shown only as screenshots or videos.
• Calls that appear after the move, or that get edited or deleted.
• Pressure to pay before you can see any past record.
• No way to see the account the results supposedly came from.

How Stock Locker does it

Stock Locker was built for these five checks. Traders connect the exchanges, brokers and wallets they really use, read-only, and their profiles show holdings and realised P&L read from those accounts. Every call is sealed with a timestamp and a SHA-256 fingerprint the moment it’s posted, can’t be edited or deleted, and opens to everyone when its timer runs out. You can look at a trader’s full record for free before paying for anything. How it works · See verified traders
