Halting a Strategy Once User Defined Conditions Are Met

Previous page Return to chapter overview Next page

For error-handling, money-management or any other reason you may want to halt your strategy from processing its' core program logic. Before you halt your strategy, it is best to close all positions and cancel all active orders to prevent the risk of having an unmanaged position in the market. We have provided two reference samples for these topics.

 

Key concepts in the SampleHaltBasicStrategy example*

Using PnL statistics to determine when to halt processing of the strategy
Cancelling active orders
Closing active positions

 

Key concepts in the SampleHaltAdvancedStrategy example**

Using a custom method to halt processing on all event-driven methods
Advanced order handling in error situations with the OnOrderUpdate() method

 

* This is intended for strategies driven exclusively by the OnBarUpdate() method.

** This sample's intended audience is for advanced programmers who have programmed strategies that take advantage of event-driven methods such as, but not limited to, OnMarketData() or OnOrderUpdate() in addition to the OnBarUpdate() method.
