A common mistake in quantitative strategies: trusting "seems reliable" data without running upstream checks.
My weather strategy previously covered 34 cities, gradually expanded over several past expansions, and I haven't reviewed it in a while. A few days ago, during a routine audit, I casually pulled the full market data from the official Polymarket API and found there are actually 44 cities — I missed 10 myself.
Even more interesting, I compared it with the weather tool site that everyone in the industry references. It also missed its biggest city: Panama City. On Polymarket, there are 66 event options for this city, and both "seems reliable" data sources didn't include it.
Lesson: the list you compiled a year ago becomes outdated, and the "industry list" compiled by others can also miss entries. Only the raw API data is correct. Running the check once doesn't cost much — this time, I pulled everything in just a few minutes.
