1. active orderbook add orders only when receive new order event or call Add/Update method manually

2. active orderbook remove orders only when receive filled/cancelled event or call Remove/Update method manually
|

|

As a result
|
||||
1. at the same twin-order-price, there is order in open orders but not in active orderbook
|
||||
- not receive new order event
|
||||
=> add order into active orderbook
|
||||
2. at the same twin-order-price, there is order in active orderbook but not in open orders
|
||||
- not receive filled event
|
||||
=> query the filled order and call Update method
|
||||
3. at the same twin-order-price, there is no order in open orders and no order in active orderbook
|
||||
- failed to create the order
|
||||
=> query the last order from trades to emit filled, and it will submit again
|
||||
- not receive new order event and the order filled before we find it.
|
||||
=> query the untracked order (also is the last order) from trades to emit filled and it will submit the reversed order
|
||||
4. at the same twin-order-price, there are different orders in open orders and active orderbook
|
||||
- should not happen !!!
|
||||
=> log error
|
||||
5. at the same twin-order-price, there is the same order in open orders and active orderbook
|
||||
- normal case
|
||||
=> no need to do anything
|
||||
|
||||
After killing pod, active orderbook must be empty. we can think it is the same as not receive new event.
|
||||
|
||||
Process
|
||||
1. build twin orderbook with pins and open orders.
|
||||
2. build twin orderbook with pins and active orders.
|
||||
3. compare above twin orderbooks to add open orders into active orderbook and update active orders.
|
||||
4. run grid recover to make sure all the twin price has its order.
