Stream Quotes (Ticks)

Subscription required

Real-time price updates for subscribed symbols.

Subscribe / Unsubscribe examples

{ "command": "Subscribe",    "extID": "1", "data": { "chanels": ["EURUSD","BTCUSD"] } }
{ "command": "SubscribeAll", "extID": "2", "data": {} }
{ "command": "Unsubscribe",  "extID": "2", "data": { "chanels": ["EURUSD"] } }
{ "command": "UnsubscribeAll", "extID": "3", "data": {} }

SubscribeAll enables delivery of quotes from all channels available to the TCP session. UnsubscribeAll clears exact channel subscriptions and disables that global mode.

Client notes

• Extremely high frequency possible (hundreds per second on volatile symbols)
• Always expect an array and verify that arr[0] === "t".
• bid/ask values are floating point numbers.
• The format is stable: no additional fields are added.
