Those are at the bottom of my list. You have better options even as a retail trader. These are my experiences with each of these from best to worst. For normalized feeds to use on the job, I'd pick one of (LSEG, Databento) first and fill in with others if needed. LSEG: Has everything. Jack of all trades and average at everything. MayStreet IP is overpriced now and I would pick anyone else in this top 7 over their MayStreet products. Databento: Overall the best API, support, and value today. Very easy to use. Limited exchange coverage and history. Bloomberg: B-PIPE is very expensive. SAPI has great value. I wouldn't use BB other than for static data, corporate actions, low frequency and spreadsheets. Options-IT/Activ: Real-time only. Better priced than Exegy but doesn't have execution. ICE/IDS: Worst support and reliability of this group, but it has good venue coverage and their consolidated feed has better all-in cost than below options. For HFT, I'd pick one of (OnixS, Broadridge, Exegy) first and fill in with others if needed. OnixS: Great value. Limited exchange coverage. Broadridge: Better API, support, coverage than Quincy and Celoxica, but not as fast. Exegy: I'd use if you need real-time data only. Quincy: Overall slightly better than Celoxica. Celoxica: About the same as Quincy. Redline: I'd use if you need real-time data only, only need US equities, and already use Pico. Outdated. Bad docs. Has execution though. For retail trading, I'd pick one of (CQG, Rithmic, Nanex, IQFeed) first and fill in with others if needed. CQG: Good value, worse API than Rithmic, but has historical data. No L3 data. Rithmic: Good value, better API than CQG, but no historical data. Nanex: Outdated. Managed C++ only. Millisecond timestamps only. IQFeed: Reliable, simple, best value for cost. dxFeed: Basically a better version of Polygon. Alpaca, Xignite: Better than other 2 in the polls. Polygon.io: Worst quality issues in this list. Intrinio: Only one on this list that isn't a licensed distributor anywhere. More on reddit.com

You might find https://alpaca.markets/ useful. They have a great entry level offering. Sadly no options trading there and they are young and have some issues when I stopped using them. More on reddit.com

Just stumbled upon Mboum's API for earnings data, and I'm thrilled! 📅 This stuff is pure gold for my investment analysis. Can't wait to crunch some numbers and see what opportunities arise! https://mboum.com More on reddit.com
