Trade Placement

Follow these steps to place a trade on Bybit perpetual futures via the Eterna MCP Gateway.

Steps

1. Check Balance

Call get_balance to determine the available USDT balance and margin. Confirm there is sufficient free margin for the intended trade.

2. Check Existing Positions

Call get_positions to see all open positions. Verify you are not already exposed to the same symbol. If a position exists, decide whether to add to it or skip.

3. Get Instrument Details

Call get_instruments for the target symbol to retrieve:

• Minimum order quantity
• Lot size (quantity step)
• Tick size (price step)
• Maximum leverage

4. Get Current Price

Call get_tickers for the target symbol to get the current mark price and last traded price.

5. Calculate Position Size

Use the following formula:

risk_amount = available_balance * risk_percentage
position_size = risk_amount / (entry_price * stop_loss_distance)

Default values:

• risk_percentage = 0.02 (2% of balance)
• stop_loss_distance = 0.006 (0.6% from entry)

Round down to the nearest valid lot size from step 3.

6. Set Leverage

Call set_leverage with the desired leverage for the symbol. Default to 10x if not specified.

7. Place the Order

Call place_order with:

• symbol -- the trading pair (e.g., BTCUSDT)
• side -- Buy (long) or Sell (short)
• orderType -- Market or Limit
• qty -- the calculated position size
• takeProfit -- target price (default 1.0% from entry)
• stopLoss -- stop price (default 0.6% from entry)

8. Verify the Position

Call get_positions to confirm the position was opened with the correct size, leverage, take-profit, and stop-loss.

Report the trade details: symbol, side, size, entry price, leverage, TP, and SL.
