This guide explains how position sizing works in copy trading, why leverage and margin settings matter, and why a copier may be liquidated earlier than the trader even when copying the same direction.
Key Concepts (USDT-M Perpetuals)
Echobit copy trading is based on USDT-M perpetual contracts. Your risk is determined by factors including:
- Position size (notional value)
- Leverage
- Margin mode (Isolated / Cross)
- Entry price & average entry price
- Fees and funding
- Mark Price (used for liquidation checks)
- Slippage and execution differences
Even if you copy the same trader, your results can differ because your account settings and executions are not identical.
How Position Size Is Calculated
1. Notional value (position value)
In USDT-M contracts, a simplified notional calculation is:
Notional (USDT) = Position Quantity X Price
Your actual quantity depends on how copy trading is configured (for example, fixed margin per order, fixed ratio, or other platform rules). Regardless of method, larger notional means larger PnL swings and higher margin requirements.
2. Initial margin (simplified)
A simplified form:
Higher leverage → lower initial margin, but also less buffer before liquidation.
Leverage Differences: Trader vs Copier
In copy trading, it is common for the trader and copier to have different leverage due to:
- copier’s personal leverage setting,
- symbol leverage limits or risk constraints,
- insufficient available margin,
- different margin mode (isolated vs cross),
- partial fills and different average entry price.
Even when copying the same trade direction, two accounts can have different liquidation prices because leverage and margin differ.
Why a Copier May Be Liquidated Earlier Than the Trader
A copier can be liquidated earlier for several reasons. The most common are below.
1. Smaller margin buffer (higher effective leverage)
If you copy with less margin relative to the same notional exposure, your effective leverage is higher:
$$\text{Effective Leverage} \approx \frac{\text{Notional}}{\text{Margin Allocated}}$$
If the trader has more margin allocated (or uses lower effective leverage), the trader can withstand a larger adverse move before liquidation. The copier, with a tighter margin buffer, may be liquidated first.
2. Different entry price due to slippage and execution timing
Copy trades are not guaranteed to fill at the same price:
- The trader’s order may fill earlier.
- The copier may fill later due to system timing and market conditions.
- Market volatility can widen the difference.
If a long position is copied at a higher entry price (or a short at a lower entry price), the copier starts with a worse cost basis, which can bring liquidation closer.
3. Partial fills and different average entry price
If the copier’s order is only partially filled at first (or filled across multiple price levels), the copier’s average entry price can differ from the trader’s, changing unrealized PnL and liquidation distance.
4. Fees and funding reduce available margin
Even if the market price is similar:
- Trading fees reduce your margin balance.
- Funding payments may be charged periodically.
Over time, funding and fees can lower the copier’s margin balance enough to trigger liquidation earlier—especially at higher leverage.
5. Margin mode differences (Isolated vs Cross)
Echobit supports Isolated and Cross margin:
- In Isolated, only the margin assigned to that position supports it. If it is insufficient, liquidation occurs even if you have funds elsewhere.
- In Cross, your available futures balance can help support multiple positions, but this also means losses can impact more of your account.
If the trader uses cross margin with a larger shared balance and the copier uses isolated (or has less cross balance), the copier may be liquidated sooner.
6. Different account balance and copy settings
Your account may differ from the trader’s due to:
- lower available balance,
- different copy multiplier/fixed margin,
- withdrawals/deposits,
- other open positions consuming margin.
These differences can cause your copied trade size, margin usage, and liquidation price to diverge.
Practical Risk Management Tips for Copiers
- Use lower leverage than the trader if you want a larger buffer against volatility.
- Prefer Isolated margin if you want to cap maximum loss per position (but remember it can liquidate sooner if margin is too small).
- Keep sufficient available margin, especially when copying multiple traders or multiple symbols.
- Monitor Mark Price, not just last price, because liquidation checks use Mark Price.
- Consider setting TP/SL to control downside and lock in profits.
- Be cautious during high volatility events; slippage and gaps can materially change entry price and risk.
