# TradeSimulation

`class TradeSimulation : Simulation`

Simulates a never ending series of trades that go pair-wise through the banks (e.g. A and B trade with each other, then B and C trade with each other, then C and A etc).

### Constructors

<init> | `TradeSimulation(runAsync: Boolean, latencyInjector: <ERROR CLASS>?)` Simulates a never ending series of trades that go pair-wise through the banks (e.g. A and B trade with each other, then B and C trade with each other, then C and A etc).

### Inherited Properties

allProtocolSteps | `val allProtocolSteps: <ERROR CLASS><<ERROR CLASS><SimulatedNode, Change>>`
bankFactory | `val bankFactory: BankFactory`
bankLocations | `val bankLocations: <ERROR CLASS>`
banks | `val banks: List<SimulatedNode>`
clocks | `val clocks: <ERROR CLASS>`
currentDateAndTime | `var currentDateAndTime: LocalDateTime` The current simulated date. By default this never changes. If you want it to change, you should do so from within your overridden iterate call. Changes in the current day surface in the dateChanges observable.
dateChanges | `val dateChanges: <ERROR CLASS><LocalDateTime>`
doneSteps | `val doneSteps: <ERROR CLASS><Collection<SimulatedNode>>`
extraNodeLabels | `val extraNodeLabels: MutableMap<SimulatedNode, String>` A place for simulations to stash human meaningful text about what the node is "thinking", which might appear in the UI somewhere.
network | `val network: <ERROR CLASS>`
networkInitialisationFinished | `val networkInitialisationFinished: <ERROR CLASS><out <ERROR CLASS>>`
networkMap | `val networkMap: SimulatedNode`
networkSendManuallyPumped | `val networkSendManuallyPumped: Boolean`
notary | `val notary: SimulatedNode`
ratesOracle | `val ratesOracle: SimulatedNode`
regulators | `val regulators: List<SimulatedNode>`
serviceProviders | `val serviceProviders: List<SimulatedNode>`

### Functions

startMainSimulation | `fun startMainSimulation(): <ERROR CLASS><Unit>` Sub-classes should override this to trigger whatever they want to simulate. This method will be invoked once the network bringup has been simulated.

### Inherited Functions

iterate | `open fun iterate(): <ERROR CLASS>?` Iterates the simulation by one step.
showConsensusFor | `fun showConsensusFor(nodes: List<SimulatedNode>): Unit`
showProgressFor | `fun showProgressFor(nodes: List<SimulatedNode>): Unit`
start | `fun start(): <ERROR CLASS><Unit>`
startTradingCircle | `fun startTradingCircle(tradeBetween: (Int, Int) -> <ERROR CLASS><out <ERROR CLASS>>): Unit` Given a function that returns a future, iterates that function with arguments like (0, 1), (1, 2), (2, 3) etc each time the returned future completes.
stop | `fun stop(): Unit`
