# QIFI
Quantaxis Differential Information Flow for Finance Intergration

QIFI 协议 作为qatrader/ qapms的标准协议, 支持股票/期货市场

- 源于快期的 DIFF协议 (Differential Information Flow for Finance)
- 名称 QIFI   为 Quantaxis Differential Information Flow for Finance Intergration

- 核心字段
	-  'accounts'

-  'events'

-  'trades'

-  'orders'

-  'positions'

-  'broker_name'
		
此协议是QUANTAXIS 未来1年以内的稳定版本, 不会更改

此协议目前也是我们内部实盘在用, 兼容风控系统的一个协议, 稳定运行半年左右

交易的协议参见[交易协议](trade_protocol.md)

###  为什么要有这个协议:

主要目的是把 策略  /  背后的账户实现解耦

策略无需关心背后的账户情况, 仅需相应的申请资源即可(如 申请模拟账户/ 申请回测账户/ 申请实盘账户/)
策略在申请完毕后, 可以直接去读取相应字段,  如 策略想获取持仓的时候 即可直接get('positions') 即为持仓字段
