GET /organization/instruments lists every instrument your organization’s
trading accounts can trade, with the specification you need to size orders and
value positions. It only includes the markets your organization is enabled for.
Requires view permission on traders, so a read-only key
can call it.
Fields
Quantities and values
Order and positionquantity is always a whole number of units:
quantity of 500 on BTCUSDT is 0.5 BTC; on MNQZ6 it is 500 contracts.
Read contractSize and pointValue from the catalogue rather than hard-coding
them.
