Categories

HFT endpoints accept a category parameter that determines which product line the call applies to.

Category	Product	Notes
`linear`	USDT-margined perpetual futures	Default for HFT accounts. All examples in these docs use `linear`.
`option`	Options	Contact your account manager to enable.

category is a required parameter on most market-data, order, position, and execution endpoints. Pass it as a query parameter on GET calls and as a JSON body field on POST calls.

Example
curl 'https://dma.coinswitch.co/v5/market/tickers?category=linear&symbol=BTCUSDT'

curl -X POST 'https://dma.coinswitch.co/v5/order/create' \
  -H 'Content-Type: application/json' \
  -d '{
    "category": "linear",
    "symbol": "BTCUSDT",
    "side": "Buy",
    "orderType": "Market",
    "qty": "0.001"
  }'

If you omit category on an endpoint that requires it, you'll get a retCode: 10001 response with retMsg indicating the missing parameter.

Coin and symbol conventions

Concept	Format	Examples
Coin	Asset code	`USDT`, `BTC`, `ETH`
Symbol	`{base}{quote}` (no separator)	`BTCUSDT`, `ETHUSDT`, `DOGEUSDT`

This differs from Spot v2 (which uses BTC/INR) and matches Futures v2 (which also uses BTCUSDT).
