I do like what I see and hear about backtrader.com. I would say they are a notable exception to my general rule of not trusting or using backtesting frameworks. However, I still think it is important to understand how the framework you are using works. So if you are using backtrader for backtesting you still need to put in the time to understand the backtesting engine. Source: over 3 years ago
What about backtrader.com? And I feel like it would be step 2 after you at least have something to backtrade and test haha. Source: over 3 years ago
Backtesting is basically applying your strategy on historical price data to see if it makes money. I've used Backtrader it works decently well: https://backtrader.com/. Source: almost 5 years ago
Some display names need a lookup table, not fuzzy strings. Pairs like Investing.com / Fusion Media Limited or Lyrie.ai / OTT Cybersecurity Inc. Share almost no tokens, so WRatio stays low and that's correct behavior. For irreconcilable aliases like that you still want GLEIF, Clearbit, or simply a maintained slug โ legal_name map. Fuzzy matching handles stylistic drift on the same name; it canโt handle unrelated... - Source: dev.to / about 2 months ago
Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / about 2 months ago
A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / about 2 months ago
Match rate of 38% in my test, but the data quality on what it does match is solid: title, seniority, industry, company size all returned cleanly. If you're already in HubSpot and enriching form fills in-place, Clearbit/Breeze is probably your lowest-friction option even at lower match rates. If you're not in HubSpot, there's no reason to choose it over PDL or Prospeo. - Source: dev.to / 2 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 3 months ago
