AWS Singapore, Availability Zone ID: apse1-az3

Price and Quantity​

IMPORTANT

Both price and quantity should be adjusted according to price_filter and lot_size_filter.
Non-adjusted price or quantity will be silently adjusted on exchange side.

Post Only​

In Bybit API Post Only orders are represented via Bybit Time In Force.
When Post Only flag is defined in an order request, it takes precedence over the specified Time In Force.
If the Post Only flag is present, the request's Time In Force is ignored and the order is placed as Post Only.

Client Order ID​

Client Order ID (orderLinkId) should be unique, with a maximum length of 36 characters.

Source and format of the Client Order ID are controlled by the orderMapperType setting:

Order Mapper TypeClient Order ID sourceRules and Restrictions
SEQUENCEOrder request's sequence numbersequence is numeric. clientOrderIdPrefix setting can be used for customization.
COMPOSITEOrder request's sourceId and orderIdsourceId and orderId are concatenated with : delimiter.

Market Maker Protection​

Market Maker Protection (MMP) is an automated mechanism designed to protect market makers against liquidity risks and over-exposure. It prevents simultaneous trade executions on quotes provided by the market maker within a short time span.

Spot Margin Trading​

Spot Margin Trading (leverageMode = MARGIN) is available only for Unified Trading Account.

Position Mode​

Position mode can be switched for USDT perpetual and Inverse futures. In one-way mode, only one position (Buy or Sell) can be open at a time. In hedge mode, both Buy and Sell positions can be open simultaneously.

There are two ways to set position mode:

  • Per order - via custom order attribute: 6340
  • Per connector - via positionMode settings
