Hi Mason ,
Like dirk_r1 said, it's a matter of opinion.
Your SL and TP should be based on the trigger(engine) of the strategy and is set after countless trials and errors.
I started developing my strategy 8 months ago and that's how long it took me to get to a satisfying version.
But this is not the final version

You have to constantly adapt to the market changes and adjust your strategy accordingly.
A little piece of advice:
- your TP and the bar/candle time are more important than SL. The SL is kinda' related to those two once you get them sorted.
- the TP should be directly proportional to the candle time. So, the lower the time is, the lower the TP is.
- you have to find a good ratio between TP and SL and the number of trades you expect your strategy to do.
- and last but not least, consider checking your strategy manually, with a little error margin to see how it works instead of using the historical tester. (checking the graph manually with your triggers and write them down on paper) I know it takes a long time, but imagine I did this with 10 min candles for 6 entire months

Every single candle !

So, in the end, without a lot of work you cannot accomplish your dreams

Cheers
