Why the data confused once several RICs were asked #40

Hi, Masters: I'm using pyrfa to subscribe data from TREP. Once I subscribe server RICs, in this case, such as 300570.SZ and 600519.SH. I found my program sometimes confused the price provider. Such as: Line1: QList(['2018-06-06T05:05:24.000000000'], dtype='datetime64[ns]'), QList([b'600519'], dtype='|S9'), QList([798.8], dtype=float32), QList([100]), QList([798.88], dtype=float32), QList([400])] Line2:[QList(['2018-06-06T05:05:27.000000000'], dtype='datetime64[ns]'), QList([b'300570'], dtype='|S9'), QList([798.67], dtype=float32), QList([400]), QList([798.88], dtype=float32), QList([400])] Line1 from 600519.SH is right, but Line2 should come from 300570.SZ

Could you please give some suggestion how to fix the problem? Thanks!

Regards Zheng

Hi, not sure how’s your program parse and cache the data from pyrfa though as we don’t see your code here. My guess is that the data is in incremental updates and you probably didn’t clear the previous value from previous update.

This was caused while I asked several RICs, the data package input from TREP, I can't tell which package belongs to which RIC. Then confusion occurred.

Yes, not clear is a problem, let me try it. Thanks!

Thanks! it was caused not clear the initial data after every update data package passed.
