 The .NET reference decoder can be found at [[https://www.nuget.org/packages/Plus500US.T4ChartDecoder]]. It mirrors the JavaScript and Python decoders (same class, handler and ``ChartDataState`` field names) for 1:1 parity across all implementations.

 === MarketMode ===
 Exchange session lifecycle state (the ``marketMode`` field in JSON, and ``state.Mode`` / ``onModeChange`` in binary).
+^ Value ^ Name             ^ Description ^
-^ Value ^ Name             ^   ^ Value ^ Name             ^
+| 0     | ``Undefined``      | No mode known yet (initial state, or an unrecognized value from the feed — the get() helpers map anything unknown here). |
-| 0     | ``Undefined``    |   | 8     | ``Failed``       |
+| 1     | ``PreOpen``        | Pre-open session: the exchange accepts, modifies, and cancels orders but does no matching. Precedes the open (often with an opening auction). |
-| 1     | ``PreOpen``      |   | 9     | ``PreCross``     |
+| 2     | ``Open``           | Normal continuous trading — orders are matched in real time. |
-| 2     | ``Open``         |   | 10    | ``Cross``        |
+| 3     | ``RestrictedOpen`` | Market is open but with restrictions on activity (e.g. limited order types or actions allowed, reduced trading session). |
-| 3     | ``RestrictedOpen`` |  | 11    | ``Expired``      |
+| 4     | ``PreClosed``      | Pre-close phase: the wind-down period just before the session closes, typically with restricted activity ahead of the closing process. |
-| 4     | ``PreClosed``    |   | 12    | ``Rejected``     |
+| 5     | ``Closed``         | Session is closed — no order entry or matching. |
-| 5     | ``Closed``       |   | 13    | ``Unavailable``  |
+| 6     | ``Suspended``      | Trading temporarily suspended by the exchange (an administrative pause, expected to resume). |
-| 6     | ``Suspended``    |   | 14    | ``NoPermission`` |
+| 7     | ``Halted``         | Trading halted — typically a volatility/circuit-breaker or regulatory halt on the instrument. |
-| 7     | ``Halted``       |   | 15    | ``TrialExpired`` |
+| 8     | ``Failed``         | The market is in a failure state (exchange or system problem; data/trading not functioning normally). |
+| 9     | ``PreCross``       | Pre-cross auction phase: orders accumulate in the book ahead of a cross (opening/closing auction), no continuous matching. |
+| 10    | ``Cross``          | The cross/auction itself is executing — orders are being matched at the auction price. |
+| 11    | ``Expired``        | The contract has expired and is no longer tradable. |
+| 12    | ``Rejected``       | The market subscription/request was rejected by the server. |
+| 13    | ``Unavailable``    | The market is unavailable — no data can be provided for it. |
+| 14    | ``NoPermission``   | Your login doesn't have permission to view or trade this market. |
+| 15    | ``TrialExpired``   | Trial access to this market's data has expired. |
