The inconsistency between the stock analysis videos on youtube is driving me nuts

It's enough that following the stock market feels like a roller coaster, especially if you own some volatile/risky stocks and i think it's causing long term irreversible damage to the brain... but lately i've been trying to learn as much as possible this skill of interpreting graphs, and yes, there are some helpful youtube videos when it comes to theory explanation. But it's not that they are wrong all the time, or right all the time. They are absolute contradictions being posted at the same time. And i'm not talking about AI channels predicting stock market crashes or the get rich fast ones. So far the worst liers, seem to be guests on mainstream media channels recordings. Somehow it feels they're trying to manipulate the market, probably because of their options trading. And even their body language is exposing them. I think the solution would be limiting the number of subscribed channels based on positive results and stick with it. BTW, I've found day traders or short term asset holders, seem to have better predictions and explanations than the rest of so called experts. Not that i'd like to be a day trader, but so far, a majority of my trades are failures. Most of them were bought at a top right before a crash and i've lost money because of bad news or other events. While my only successful trades were the ones mirroring people signaling sector shifts and recommending the best company in the sector based on available data, like oil right now. Now if there could be a valid strategy to determine when to exit that sector right in like with the wales..... and knowing a dump from a volatile week... that's a different discussion. What's your take on this for a beginner like me?
