The daily threshold file published by Nasdaq Trader (nasdaqtrader.com/dynamic/symdir/regsho/nasdaqth<YYYYMMDD>.txt), the official Reg SHO daily list for Nasdaq-listed securities. Leave date blank and the run takes the most recent published file (it looks back up to 7 calendar days, since no file is published on weekends or market holidays).

📊 What you get

Clean JSON, one record per threshold security (5 fields):

• symbol — ticker
• securityName — issuer / security name as published
• marketCategory — Nasdaq market tier code (Q / G / S)
• regShoThresholdFlag — threshold flag as published (Y)
• fileDate — the YYYYMMDD file the record came from

Pricing: $0.05 per record (Pay-Per-Event) — about 20 records per $1. Plus a $0.01 Actor start (charged by the platform, one event per GB of memory).

✅ How the run ends

• Rows found → SUCCEEDED with the record count and file date in the status message.
• File published but listing no securities → SUCCEEDED with 0 rows and a message saying so; nothing is charged.
• Nasdaq Trader unreachable or blocking → the run FAILS with the cause in the status message, instead of quietly returning an empty dataset.
