You can backtest without programming skills and you do not need to know programming to start simulator trading.
First, know the rules of your trade strategy. Next, if you do not have historical data...start keeping basic stats of the pattern you see on your charts for each trading day going forward (start doing it tomorrow).
Next, get a professional trade journal software that works with simulator trading at your broker. That professional trade journal software will do the quantitative statistical analysis for you about your simulator or real money trade performance.

There's a few out there freely shared that are excel but that was years ago.
Yet, today's brokers usually have some kind'uv basic statistical analysis embedded in their platform that gives you win:loss ratios, MAEs, MFEs, average time in trades, number of Longs, number of Shorts...basic stuff like that regardless if you use it or not to look deeper into your trade performance via whatever trade strategy you're using.
It all starts with your trade strategy. If you really do not have one and have just been winging it sort'uv speak...trading will be the hardest thing you've ever done.
