This feature allows users to pause a running strategy using the command exit --suspend. This allows the bot to stop while keeping the hanging orders in the order book. To resume, run the command start --restore.
Note
Currently, this feature only works with pure market making strategy.
Pause #
The exit --suspend command will “pause” the strategy and exit the Nonstop Algo client. All active orders will become hanging orders while hanging orders will stay hanging when resumed at a later time.
This could be an advantage if you don’t want to cancel orders but want to exit the bot.
Resume #
To resume a “paused” strategy, import the config file and run the command start --restore. It will create new sets of active orders on top of the hanging orders from when it was paused.
Note
After running start --restore spreads may change once the bot brings back your orders, it will display what the current spreads of your order.
You can see that when we use exit --suspend it exits the bot. When you run start --restore all active orders became hanging orders.
Important notes #
Always use start --restore when resuming a paused strategy. Accidentally running the start command after importing the config file will cancel all of its dangling orders and start the strategy from a fresh state. See example below,
These are the orders before we run exit --suspend
Orders:
Level Type Price Spread Amount (Orig) Amount (Adj) Age
2 sell 0.3401 0.59% 46.0 46 00:00:03
1 sell 0.3398 0.50% 45.0 45 00:00:03
You will notice that when we use start it will show on the logs that orders are cancelled.
Note
Running start --restore on a different configuration file wont work, You should always use the same config file where the exit --suspend is executed.
