Using a minimal cost prop trading provider could be an option. And it can serve as an incentive to try and get some form of funded account. There are some very cost effective options out there. Oneuptrader had a $19/month special with a Rithmic datafeed and L2 enabled. (The 'sale' is no longer on.) They call it a $25K account, one can trade up for 30 micros, and try to attain $1500 profit. Another currently cheap option is TheFuturesDesk offering a similar account for $25/month, and then $29/month extensions. They too offer 'free' L2 Rithmic. I'm only offering these as alternatives to paying for a monthly L2 datafeed, with I believe are all over $60.
I used to use CQG free trials, constantly renewing them biweekly or monthly, by going to a landing page like this, under a VPN that changed the location they saw I was applying for, and then use different names & email addresses, and you should be able to constantly renew. https://www.ampfutures.com/why-amp/cqg-data-quality
Here's that current $25/$29 offer from TheFuturesDesk:
