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 Limitqty -- the calculated position sizetakeProfit -- 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.
