I have been using Topstep Trader Funding as a prop firm. So far the rules and the trading have been excellent. Topstep uses a daily loss limit which if it’s breached doesn’t cancel the account but just shuts down your trading for the day. The only simple rule to pass the evaluation is don’t reach your maximum drawdown. The monthly subscription fee is very reasonable and once in a funded account just need to pay for professional data on a monthly basis. For Tradovate and Trading View the monthly fee is $122 which is reasonable as well as easy to earn throughout the month. I personally use the Tradovate platform but there are many platforms available which is very nice. Most firms only use 1 or 2 platforms such as MT4 or MT5 or Ninjatrader. Having options makes it a very attractive firm to use.
