Idea¶
Handle by get the exchange then out immediately¶
First get the metadata of exchange that expectly in.
| Exchange code | Rejected to submit task |
|---|---|
| HOSE | No |
| HOSE | No |
| OTC | Yes |
Reject by the financial instrument type¶
| Exchange code | Rejected to submit task |
|---|---|
| Common Stock | No |
| Funds | Yes |
| Derivaties | Yes. Can be filter by URL [https://finance.vietstock.vn/derivatives/VN30F1M/futures.htm] |
| Bond | Yes |
Example: IPAAM VN100 (HOSE: FUEIP100
Wait time of sequences approach¶
When the task has been run (aka 30 times) then call a process to wait
Detect accepted ranges of updated data¶
At the current value, find the fiscal updated data, then build the accepted ranges of updated dataset.
Example:
At June 19th, 2024, the fiscal updated data is 2024-Q1, then construct the accepted range of [2024-Q1, 2023-Q3, 2023-Q1]
Compare 2 stage of numbers:
-
First get the latest updated data point, mark as
FROM_SOURCE -
Then get the latest updated data point in the database, mark as
FROM_INTERNAL
If the period is the same then out of the task and mask ALIGN_WITH_SOURCE
If not, validate the FROM_SOURCE is in UPDATE_WITH_MARKET
This supported fast updated time of component
Has the report of each run sequences¶
At the each flow, then build a updated reports with following metadata
| Code | Description |
|---|---|
ALIGN_WITH_SOURCE | There is no update from source |
UPDATE_WITH_MARKET | Updated with market |
NOT_EXISTED_RUN_LAST_7D | Not existed run last 7D |
Build reject values in any style (memory, file, database)¶
This will reject the value
Troubleshooting¶
Crash: OTC not has metadata of the fundamental snapshot¶
Example: YSC in OTC
selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crash¶
This case can be the true case of a requried run.
This can be filter by the errors then re-updated if in the required updated case.
Example: VPB has failed
