How much of your portfolio should you allocate to one copied trader
There is no official number. There is a number you can defend on a bad week, written down before you copy.
Nobody can hand you a correct percentage. What follows is how to pick one you can still defend at the bottom of a bad month.
Set two numbers, not one
The first number is how much of your total capital sits in copy trading at all. The second is how much of that sits with one trader.
Most beginners only ever set the second one, and only by accident — they fund one trader and stop there. That is 100%, undeclared.
The three defaults SafeCopy starts you with
| Rule | Default | The reasoning |
|---|---|---|
| Copy trading share of total capital | 20% | Copying is one strategy among several, not the whole portfolio. |
| Maximum per copied trader | 30% of the copy account | Three or four traders can each have a bad run without ending the account. |
| Global stop on the copy account | -15% | A number you agree to while calm, so you do not have to invent one while panicking. |
Scroll the table sideways to read every column
These are defaults, not recommendations. Change all three. What matters is that a number exists before the money moves.
Why one trader holding everything breaks, even when the trader is good
A trader with a real edge can still fall -30% over four months. That is not failure, that is variance doing its normal work.
If that trader holds all of your copy capital, that -30% is your whole account. Almost nobody sits through it.
Spread across 3 traders at 30% each, the same -30% costs you -9%. Same trader, same month, a number you can hold.
Correlation is the trap the leaderboard hides
Four traders who all go long the same crypto majors are one trader with four names. Read what they trade, not only their curve.
- Do they trade the same instruments?
- The same direction, most of the time?
- The same session, on the same news?
- Through the same broker, with the same funding risk?
If the answer is yes four times, your real allocation to that idea is the sum, not the largest slice.
Allocation drifts even when you do nothing
A winning trader grows its share of your copy account. A losing one shrinks. Nobody rebalances by accident.
So the rule needs two halves: the number you declared, and a weekly look at the real number against it.
A breach is not a verdict on the trader. It says one position outgrew the limit you set for yourself, and names by how much.
What to do in the next 10 minutes

- 2Write your maximum per copied trader as a percentage of the copy account.
- 3Write the drawdown at which you stop copying and review.
