Copy Trading Lot Size and Risk Settings, Explained Properly

What a lot actually is

A lot is a unit of position size. In forex, one standard lot is 100,000 units of the base currency. You will also meet mini lots (0.1) and micro lots (0.01).

The practical meaning is what one pip of movement is worth to you:

These are approximate and depend on the pair. Gold behaves differently again — XAUUSD pip values are worked through separately here, and the difference catches people out badly.

The part that confuses everyone: proportional copying

The strategy account is usually much larger than yours. If it opens a 1.0 lot position and your account copied that literally, one bad move could wipe you out.

So platforms scale. If the strategy has $100,000 and you have $1,000, you have 1% of its size, and its 1.0 lot trade becomes 0.01 lots in your account. Your percentage gain or loss then roughly matches theirs, which is the point.

What to check: that scaling is actually proportional and not fixed. A fixed-lot setting copying a much larger account is the fastest way to lose everything, because you take their position sizes on your balance.

The settings, and which ones matter

• Allocation. How much of your balance follows this strategy. Not everything, especially not first time. Keeping some balance unallocated is what lets you survive a bad stretch without a margin call.
• Multiplier. Copy at the strategy's proportional size (1×), less, or more. Above 1× multiplies losses exactly as much as gains. There is no setting here that improves your odds — only ones that change the size of the outcome.
• Stop-out / maximum drawdown. Copying halts automatically at a loss level you set. This is the most valuable setting on the screen. It converts an unlimited bad scenario into a defined one.
• Maximum position count. Caps how many trades can be open at once. Useful because several open positions on correlated instruments is a much bigger bet than it looks.

A sensible starting point

Not advice — a conservative default to adjust from once you understand your own reaction to losses:

1. Allocate a portion of your balance, not all of it.
2. Multiplier at 1×. Leave it there until you have watched the strategy through a full losing period.
3. Set the stop-out. Choose a number that would hurt but not matter — and set it before you are emotionally invested.
4. Write down why you chose those numbers. When you feel the urge to raise the multiplier after a good month, that note is what argues back.

One warning about leverage

Leverage settings interact with everything above. Higher leverage lets the same deposit control a larger position, which multiplies both directions equally. It is the single most common reason beginner accounts go to zero.
