How to get high-quality historical quotes for testing?

[MelanieBriggs234]

I ran into an issue recently while backtesting a strategy. I thought I had a solid plan, tested it on historical data, and everything looked great. But when I switched to a live account, the results were completely different. After some digging, I realized the problem wasn’t my strategy—it was the data itself. The historical quotes I was using had gaps, missing price movements, and inaccurate spreads. No wonder my results didn’t match reality. Now I’m trying to figure out where to get reliable, high-quality historical data for testing. Any recommendations?

Yeah, I’ve been through that too. A lot of free data sources out there seem fine at first, but once you dig into them, you realize they’re missing key details like accurate spreads or tick data. I learned the hard way that using low-quality historical data can make a strategy look much better (or worse) than it actually is.

From my experience, it’s worth investing in good data, especially if you want to avoid surprises when switching to live trading.

Interesting topic! I think a lot of traders underestimate how important data quality is. It’s not just about having enough historical information—it’s about having accurate, realistic data that actually reflects market conditions. It’s kind of like training for a race with the wrong course map—if your preparation isn’t based on reality, you’re setting yourself up for problems when it really matters.
