Syntax

Gemini

Spot trading on Gemini (API address https://api.gemini.com). It uses REST only, with no market-data or order push. Private endpoints are signed with a Gemini API key (Access Key and Secret Key). With a master API key (starting with master-), exchange.IO("subAccount", name) selects the sub-account to operate on. Market orders and conditional orders are not supported.

Names and Configuration

exchange.GetName(): Gemini (Spot).

Field	Required
Access Key	Yes
Secret Key	Yes

Trading Pairs and Contract Codes

Pair examples: BTC_USD, ETH_BTC, BTC_USDT

Trading pairs are written BASE_QUOTE, matching the Gemini native code btcusd.

Exchange-specific IO Commands

Command	Arguments	Description	Returns
`subAccount`	string	Set the sub-account name. Only takes effect with a master API key (an Access Key starting with `master-`), whose private requests then carry this sub-account; `primary` is used when not set.	A null value.

For the common commands api, base and currency see exchange.IO.

Common Usage

Operate a sub-account with a master API key


            javascript
            
            
function main() {
    // Only for a master key (Access Key starting with master-): later private requests
    // carry this sub-account
    exchange.IO("subAccount", "my-sub-account")
    Log(exchange.GetAccount())
    // Back to the default, primary
    exchange.IO("subAccount", "primary")
}

Function Support

Not supported (the call fails with an error and returns null): exchange.GetTickers, exchange.ModifyOrder, exchange.CreateConditionOrder, exchange.ModifyConditionOrder, exchange.CancelConditionOrder, exchange.GetConditionOrder, exchange.GetConditionOrders, exchange.GetHistoryConditionOrders.

Served through a fallback:

exchange.GetRecords: Native periods are 1m, 5m, 15m, 30m, 1h, 6h, 1d; other periods are synthesized by the docker.

Notes

Market orders are not supported, only limit orders; IOC, FOK and maker-only (postOnly) are supported.
exchange.GetHistoryOrders() does not support the since argument and fails when it is given; at most 500 orders are returned per call.
The K-line endpoint has no paging, so each period only gives the most recent batch the exchange returns (about the last day for 1-minute K-lines).
exchange.GetMarkets() returns only the spot pairs whose status is open, not Gemini's perpetual contracts; precision and similar details are queried from the exchange one pair at a time, so the call takes a while.
In exchange.GetTrades(), trades from auction matching have no taker side, so their Type is 2.
