- proverbialbunny 6y agoCool! Know of any cheap 1 sec bar or less historical data sources? IBS does live tick data for around $10 a month, smaller than 1sec. I hate IBS, but I hate paying $200 a month more, especially when I'm backtesting most months.
- nemothekid 6y agoI came across https://tradier.com/products/brokerage-api https://tradier.com/products/brokerage-api which seems to provide historical data for free. I'm taking a look currently, so I'm unsure how good the data is.
