Stock Quotes (Go SDK)

Get real-time price quotes for multiple stock symbols in a single API request.

Making Requests

Both call styles live on the Stocks service (client.Stocks). Use GetQuotes for the simplest call, or Quotes when you need functional options or the raw response and rate-limit metadata.

Method	Return	Description
GetQuotes(symbols...)	([]Quote, error)	Convenience wrapper; takes symbols variadically, uses context.Background(), and does not accept options.
Quotes(ctx, symbols, opts...)	([]Quote, *response.Response, error)	Context-aware; accepts options and also returns the raw response + rate-limit metadata.

Quotes

func (s *Service) Quotes(ctx context.Context, symbols []string, opts ...QuoteOption) ([]Quote, *response.Response, error)
func (s *Service) GetQuotes(symbols ...string) ([]Quote, error)

Fetch real-time quotes for many symbols at once.

Parameters

• ctx (context.Context) — controls cancellation and deadlines (context method only).
• symbols ([]string for Quotes, variadic ...string for GetQuotes) — the stock ticker symbols, e.g. []string{"AAPL", "MSFT", "GOOG"}. At least one symbol is required; an empty set returns a validation error without making a request.
• Options (stocks.QuoteOption, Quotes only — GetQuotes accepts no options):
  • stocks.WithFiftyTwoWeek(enabled bool) — request 52-week high/low data for each quote. Defaults to off.
  • stocks.WithExtended(extended bool) — control whether quotes include extended-hours data. When omitted, the parameter is not sent and the API default applies.

Returns

• []Quote — one Quote per symbol returned by the API.
• *response.Response — raw response + rate-limit metadata (context method only).
• error — non-nil on request/validation failure.

Notes

• If the API responds with 404 because no data is available, Quotes returns a nil slice, a nil error, and a non-nil *response.Response whose NoData field is true. GetQuotes discards that metadata, so a no-data result is simply a nil slice with a nil error.
• To pass options and still request multiple symbols, use Quotes — GetQuotes is options-free by design.

Get (simple)

package main

import (
	"fmt"
	"log"

	"github.com/MarketDataApp/sdk-go/v2/marketdata"
)

func main() {
	client, err := marketdata.NewClient(marketdata.WithToken("YOUR_TOKEN"))
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	quotes, err := client.Stocks.GetQuotes("AAPL", "MSFT", "GOOG")
	if err != nil {
		log.Fatal(err)
	}

	for _, q := range quotes {
		fmt.Printf("%s: $%.2f (%.2f%%)\n", q.Symbol, q.Last, q.ChangePercent)
	}
}

Output

AAPL: $186.19 (0.57%)
MSFT: $380.55 (0.61%)
GOOG: $143.12 (-0.31%)

Context + Response

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/MarketDataApp/sdk-go/v2/marketdata"
)

func main() {
	client, err := marketdata.NewClient(marketdata.WithToken("YOUR_TOKEN"))
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	ctx := context.Background()

	quotes, resp, err := client.Stocks.Quotes(ctx, []string{"AAPL", "MSFT", "GOOG"})
	if err != nil {
		log.Fatal(err)
	}
	if resp.NoData {
		fmt.Println("no quotes available")
		return
	}

	for _, q := range quotes {
		fmt.Println(q) // Quote implements Stringer
	}
	fmt.Printf("Requests remaining: %d\n", resp.RateLimit.Remaining)
}

With options

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/MarketDataApp/sdk-go/v2/marketdata"
	"github.com/MarketDataApp/sdk-go/v2/marketdata/stocks"
)

func main() {
	client, err := marketdata.NewClient(marketdata.WithToken("YOUR_TOKEN"))
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	ctx := context.Background()

	watchlist := []string{"AAPL", "MSFT", "GOOG"}
	quotes, _, err := client.Stocks.Quotes(ctx, watchlist,
		stocks.WithFiftyTwoWeek(true),
	)
	if err != nil {
		log.Fatal(err)
	}

	for _, q := range quotes {
		pctFromHigh := (q.Last - q.FiftyTwoWeekHigh) / q.FiftyTwoWeekHigh * 100
		fmt.Printf("%-5s $%8.2f  52wk %.2f-%.2f  (%+.1f%% from high)\n",
			q.Symbol, q.Last, q.FiftyTwoWeekLow, q.FiftyTwoWeekHigh, pctFromHigh)
	}
}

Quote

Quotes returns a slice of the same Quote value used by the single-symbol Quote endpoint.

type Quote struct {
	Symbol           string    `json:"symbol"`      // Stock ticker symbol
	Ask              float64   `json:"ask"`         // Current ask price
	AskSize          int       `json:"askSize"`     // Size of the ask
	Bid              float64   `json:"bid"`         // Current bid price
	BidSize          int       `json:"bidSize"`     // Size of the bid
	Mid              float64   `json:"mid"`         // Midpoint between bid and ask
	Last             float64   `json:"last"`        // Last trade price
	Change           float64   `json:"change"`      // Price change from previous close
	ChangePercent    float64   `json:"changepct"`   // Percentage change from previous close
	Volume           int64     `json:"volume"`      // Trading volume
	Updated          time.Time `json:"updated"`     // When the quote was last updated
	FiftyTwoWeekHigh float64   `json:"52weekHigh,omitempty"` // 52-week high (WithFiftyTwoWeek)
	FiftyTwoWeekLow  float64   `json:"52weekLow,omitempty"`  // 52-week low (WithFiftyTwoWeek)
}

Fields

• Symbol — the stock ticker symbol.
• Ask / AskSize — the current ask price and the number of shares offered at it.
• Bid / BidSize — the current bid price and the number of shares bid at it.
• Mid — the midpoint between bid and ask.
• Last — the last traded price.
• Change — price change in dollars from the previous close.
• ChangePercent — the change from the previous close (JSON alias changepct).
• Volume — trading volume for the session.
• Updated — timestamp of the quote (US Eastern).
• FiftyTwoWeekHigh / FiftyTwoWeekLow — 52-week high/low, present only with WithFiftyTwoWeek.

Helper Methods

• Spread() float64 — the bid-ask spread (Ask - Bid).
• SpreadPercent() float64 — the spread as a percentage of Mid.
• String() string — a one-line summary of the quote.
