I think forex is a good job. With 50 and 200, you usually have to use a larger time period. so the first thing to set before choosing a setting for moving averages is knowing in what time period we will trade. for shorter periods of time I would recommend LWMA 34, 19 and 8. And this works for me, I use two moving averages. I use 50 EMA and 200 EMA. When 50 EMA is above 200 EMA then I think the trend is up. This is the right way to learn rather than jumping around from one indicator to another looking for the holy grail. If you want to know the current support and resistance levels, then you should know about Bollinger bands.
