Market State block
The Market State block is a trading block that lets you check whether the market is currently in a particular state and outputs a Boolean value. For example, you can use the block to see if the market is open, close, or halted.
The following example uses the Market State block to enable an Order block only if the market is open.
Example A Market State block with properties set to check for a market state of 'open' recieves an instrument's market data. The market state included in the instrument data matches 'open' so the Market State block outputs a Boolean value of 'True' to the Order block.
- Disables the Order block if the market is closed
When using a Market State block, the Ignore Market State option for the algo should be enabled. This option is disabled by default, which causes the algorithm to pause automatically when any market reported by an Instrument block in the algorithm is not in a trading session. However, because the Market State block is typically used to execute logic outside of a regular trading sessions, the Market State block will be rendered ineffective when the Ignore Market State option is disabled.
