Receiving the following errors from mongo it appears. See below:

Any advice?

Also, once the orders are filled on both sides, it does not resubmit the grid for new orders. It only says 'on open' in the terminal, but never places new order sets. @fengok

你好，策略运行需要设置Mongodb数据库，在Quant.py 的31行开始是相关代码，在_websocket.py 的195行是相关代码，okex_websocket的218行是相关代码，你可以查看一下，websocket改变数据库的订单状态，Quant.py检测数据库的订单状态是否发生变化去进行相关操作

@fengok Thank you, I got it working now.

However, noticing when orders are filled on either side, the algo does not update the orders to maintain the spread. Is this correct? If so, it will get orders stuck in positions often when market goes against your grid.

@caressgents 别客气！现在价格超出了网的范围，就不会运行了，没有附加价格跟随功能，没有止损功能，你可以尝试添加，以后我可能会更新
