Description
❓ Questions and Help
When I calculate the Alpha158 factors, the system always freezes, then the screen goes black, and I have to force a shutdown. This happens even when calculating factors for just a few stocks over a couple of days. What could be the reason? Here is my code:
`stock_list = ["SH000001", "SZ399001", "SH000300"]
start_time = "2018-12-26"
end_time = "2018-12-27"
handler = Alpha158(
instruments=instruments,
start_time=start_time,
end_time=end_time
)`

Research direction
Start by reproducing the issue through the Alpha158 entry point with the three instruments and the 2018-12-26 to 2018-12-27 range shown in the report. The payload names no source file or test, so trace Alpha158 factor calculation and resource use from that entry point. Done means identifying the cause of the freeze and confirming the calculation completes for the reported small input.
