WsIndicatorSubscribe

StockSharp.Ws

Client-to-server command (envelope type = "indicatorSubscribe"): subscribe a live indicator on (SecurityId, TimeFrame, Spec). Server primes the indicator with history, returns a WsIndicatorSeries for the warm-up, then streams WsIndicatorPoint messages as bars finalise. Send the same command with IsSubscribe= + OriginalTransactionId matching the original sub's TransactionId to unsubscribe.

Properties

From

public DateTime? From { get; set; }

value = wsIndicatorSubscribe.From
wsIndicatorSubscribe.From = value

Wire field from. Optional — if set, server uses this as the history-window start when priming the indicator. Default is implementation-defined (server picks a sensible warm-up window).

IsSubscribe

public bool IsSubscribe { get; set; }

value = wsIndicatorSubscribe.IsSubscribe
wsIndicatorSubscribe.IsSubscribe = value

Wire field isSubscribe. Default ; for unsubscribe.

OriginalTransactionId

public long? OriginalTransactionId { get; set; }

value = wsIndicatorSubscribe.OriginalTransactionId
wsIndicatorSubscribe.OriginalTransactionId = value

wsIndicatorSubscribe.TimeFrame = value

Wire field timeFrame. ISO-8601 duration ("PT1M") or compact form ("1m", "15m", "1h", "1d"). Server parses both.

Wire field transactionId. Client-allocated id; echoed in responses.
