Best brokerages for active algorithmic trading

Hi guys,
I've gotten heavily into algorithmic trading over the last year and I'm looking for a new broker. I'm not sure if what I do would be considered high frequency trading but I've made up to 20,000 trades in a day and the opportunities I go after gnerally persist from 50-300ms. I'm currently trading about 20 million shares of US Equities and ETFs per month and using Ameritrade and Tradestation.

I need to be able to trade in lots as small as 100 shares, have a commission of 10 mils or less with no per-trade minimum, competitive fees and rebates on major exchanges, good selection of dark pools, ability to route orders without extra cost and preferably have access to a python-compatible API rather than using FIX. Colocation is a big plus although if the servers are located next to a major cloud provider I am okay with latency up to 30ms.

I'm currently looking at Lime, Dash Prime, Atreyu, and Sage/Clear Street, but none of these is a perfect fit for me.

Interactive broker's commission structure doesn't work for me (.35 minimum and 50 mils to route your own orders). Lightspeed is better but their fees/rebates and dark venues are not very competitive.

I would love to hear what other brokerages people on here are using that would be a good fit for the kind of trading I'm doing.

Thanks
Are you providing liquidity on all your trades?
 
Hilarious how someone flaunts large numbers and immediately the canal rats are crawling out of some holes. Like swinging a dildo in front of a horny woman.
 
What's average speed of orders execution with your brokers? Any FX brokers which offer execution of CFDs within 100 ms? Most brokers I checked execute orders within 350-1200 ms bad which is too slow..

I trade 500(Use to hit 2000) plus day trades average size varies 3000 ACY to 100,000 sometimes 500,000 on highly liquid stocks like SNDL where 2.5 million surround round points. I would love to know how to pay $.001 tearing off offers and slamming bids without paying as high as $5,000 in commission RT. Is some broker going to lose $.002 each trade and make it up in volume for me? Commission is why the Op is at Ameritrade on another post on leveraged ETF orders issues. If Dave Portnay uses Zero Commission how will the Op find one charging $.001 on market orders because Davey has not.

Manual, it use to be stressful as help hitting “fast keys” like Whack A Mole! Dropped down to 500 sometimes more or less. I thought the Op was April Fooling us because his strategy from his ETF post was buying “5000” shares of Leverage ETFs at Market.

On Ameritrade I do large trade sizes because they limit the number of trades per day. On tradestation I do 100 shares per trade since there is no limit.
