Module Std.Tws

module Tws: Tws

module Query_id: Core.Std.Unique_id 
type t 
A TWS client

Connection and server


val with_client : ?do_logging:bool ->
?client_id:Client_id.t ->
host:string ->
port:int ->
on_handler_error:[ `Call of Core.Std.Error.t -> unit | `Ignore | `Raise ] ->
(t -> unit Async.Std.Deferred.t) -> unit Async.Std.Deferred.t
with_client ~host ~port ~on_handler_error handler connects to the TWS software on (host, port) and runs the handler until an exception is raised or the returned Deferred.t is determined.

on_handler_error determines what happens if the handler raises an exception.

The standard port for the TWS software is 7496. You can connect IB Gateway on port 4001 as an low-resource alternative compared to TWS.

val with_client_or_error : ?do_logging:bool ->
?client_id:Client_id.t ->
host:string ->
port:int ->
(t -> unit Async.Std.Deferred.t) ->
unit Core.Std.Or_error.t Async.Std.Deferred.t
Same as with_client, but returns an Error if the connection was not successful or an exception was raised in the handler.
val is_connected : t -> bool
is_connected t checks whether the TWS client t is connected.
val state : t -> [ `Connected | `Connecting | `Disconnected ]
state t returns the connection of the TWS client t.
val set_server_log_level : t ->
level:[ `Detail | `Error | `Information | `System | `Warning ] -> unit
set_server_log_level level sets the log entry detail level of the TWS software when processing API requests.
val server_time : t -> Core.Std.Time.t Core.Std.Or_error.t Async.Std.Deferred.t
server_time t returns the current time from the TWS server or an Error.
val server_time_exn : t -> Core.Std.Time.t Async.Std.Deferred.t
Same as server_time, but raises an exception if an Error was returned.
val server_version : t -> int option
server_version t returns the version of the TWS server upon successful connection of the TWS client t, otherwise None is returned.
val connection_time : t -> Core.Std.Time.t option
connection_time t returns the time the client t was connected to TWS or None when no connection was established.
val account_code : t -> Account_code.t option
account_code t returns the code of the Interactive Brokers account upon successful connection of the TWS client t, otherwise None is returned.

Market data

Core.Std.Or_error.t Async.Std.Deferred.t
market_data t contract requests streaming market data from TWS for the given contract. Streaming market data is written to a Pipe.t that is returned together with a query id used to cancel the request via cancel_market_data from below.

When snapshot is set to True the market data pipe contains only the latest snapshot of the data.

If futher tick_types are supplied the marke data pipe is extended with their current values.

underlying_price:Price.t -> Price.t Core.Std.Or_error.t Async.Std.Deferred.t
option_price t contract volatility price asks TWS to calculate the option price for the given contract based on the given volatility and current price of the option's underlying. An Error is returned whenever something goes wrong.
