What is a good algorithmic trading platform for someone who doesn’t understand programming, but has experience with trading?

I am looking for something that I can set up to automate stock and option trades on rules that I preestablish. Nothing too crazy. One main issue I have is losing money around the opening bell on options trades. If I could create something that could automate what Charles Schwab would probably call a trailing stop walking limit it would be perfect. I’m looking to begin putting a little more money into strategies I am using, and manually attempting to trade or using some of Charles Schwab Think or Swim features isn’t working. In the morning certain market makers will place wide and unrealistic bid ask spreads, which will trigger my trailing stop orders. To get around it for selling, I essentially spend hours making conditional normal limit orders that expire at 10:15am and then will have trailing stop limits that come into play at 10:15am. Then for buying I either just stay away or try to manually follow a morning price movement. I am pretty programming illiterate, so am looking for something a little more user friendly or geared towards beginners. Per another comment I saw, was planning to get “Theta Data” for real time pricing so something that works with that. Also if there where any good guides or resources people would suggest, would love to hear them.
