Poloniex

Spot trading on Poloniex (API address https://api.poloniex.com, v3 API); orders are placed in the SPOT account (accountType is SPOT). It uses REST only, with no market-data or order push. Private endpoints are signed with a Poloniex API key (Access Key and Secret Key). Conditional orders use Poloniex smart orders (/smartorders) and support stop-loss only.

Names and Configuration

exchange.GetName(): Poloniex (Spot).

Trading Pairs and Contract Codes

Pair examples: BTC_USDT, ETH_USDT

Trading pairs are written BASE_QUOTE, the same form as the Poloniex native code.

Exchange-specific IO Commands

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

Common Usage

List the spot accounts and choose the one exchange.GetAccount() reads

            javascript
            
            
function main() {
    // The exchange's account list; each item has accountId, accountType (such as SPOT)
    // and accountState
    var accounts = exchange.IO("api", "GET", "/accounts")
    Log(accounts)
    // From now on exchange.GetAccount() reads only this spot account (an error if not found)
    exchange.IO("accountId", accounts[0].accountId)
    Log(exchange.GetAccount())
    // An empty string restores the default (the first spot account)
    exchange.IO("accountId", "")
}

Function Support

Not supported (the call fails with an error and returns null): exchange.ModifyConditionOrder.

Served through a fallback:

• exchange.GetRecords: Native periods are 1m, 5m, 10m, 15m, 30m, 1h, 2h, 4h, 6h, 12h, 1d, 3d, 1w, 1M; other periods are synthesized by the docker.

Notes

• The amount of a market buy order is the quote currency to spend (placed as Poloniex's amount); a market sell order uses the base-currency quantity.
• Limit orders support IOC, FOK and maker-only (postOnly).
• exchange.ModifyOrder() uses Poloniex's replace endpoint: the exchange cancels the original order and places a new one, and the new order ID is returned; use the new ID from then on. A price or amount that is not positive is left unchanged. The amended amount is always the base-currency quantity (Poloniex's quantity), including when only the amount of a buy order is changed.
• Spot conditional orders support stop-loss only (ORDER_CONDITION_TYPE_SL): a buy triggers when the price rises to the trigger price, a sell when it falls to the trigger price. Take-profit (ORDER_CONDITION_TYPE_TP) and OCO conditional orders return an error and no order is placed. Without an order price they execute at market once triggered. The amount of a conditional order is always the base-currency quantity, for both buys and sells.
• Conditional orders and normal orders have separate order IDs: a conditional order can only be canceled with exchange.CancelConditionOrder. The normal order created when a conditional order triggers appears in exchange.GetOrders(), while exchange.GetConditionOrders() lists only untriggered conditional orders.
• exchange.GetAccount() reads one SPOT account: the one set with exchange.IO("accountId", id), or the first SPOT account when none is set; exchange.GetAssets() sums the assets of all SPOT accounts.
