How Position Sizing and Risk Limits Work in Copy Trading

The biggest fear new copy traders have is simple: what if I copy someone with a much bigger account and one of their trades wipes me out? Good copy-trading software answers that with sizing and risk controls that sit between the trader’s signal and your account. On RelayTrades those controls run server-side, before any order is placed.

Position sizing: copying proportionally, not identically

You do not copy the trader’s raw share or contract count. Instead you scale their trades to your own account using a sizing multiplier, so a trader with a large account does not force oversized positions into a small one. You can dial the multiplier up or down to match your risk comfort, and set a maximum dollar amount so no single copied position can exceed an amount you choose.

The risk limits that run before every order

• Sizing multiplier: scales each copied position relative to the trader’s, up or down to fit your account.
• Maximum dollar per trade: a hard ceiling on how large any single copied position can be.
• Exposure and daily-loss caps: limits on how much can be at risk overall and how much you are willing to lose in a day.
• Slippage protection: guards against filling a copied order at a price far from the intended one.
• Auto or manual execution: let copies route automatically within your limits, or require your approval on each one within a short window.

These checks are enforced server-side. If a copied trade would breach one of your limits, it is capped or skipped, not blindly mirrored.

Auto vs manual, and the kill switch

You decide how hands-on to be. In automatic mode, copied trades route to your account on their own as long as they fit your limits. In manual mode, each copied trade waits for your approval for a short window before it can be placed, which trades a little speed for a final human check. And whatever mode you are in, a one-tap kill switch halts all automation and flattens open positions on your account instantly, so you are never locked in.

Controls contain risk, they do not erase it

Risk limits are powerful, but they are not a profit guarantee. They keep a single trade or a single bad day from doing outsized damage; they cannot make a losing strategy win. You can still lose money copy trading, and past performance is not indicative of future results. The right way to use these controls is to set them deliberately before you start, in line with what you can genuinely afford to lose.
