Trading strategies are generally standard and consistent, but it's the implementation that makes people ineffective due to a lack of understanding. No new strategy can be tested because we only follow a few existing strategies, and this reveals the misapplications each individual makes. What we need to do is practice discipline and adapt our trading to strategies that are more relevant to our trading style, as this can minimize risk. Every strategy carries risks, as trading isn't always profitable. However, these risks can be minimized to prevent further financial losses. I prefer to see people making small amounts of money in trading but consistently persisting, as this allows them to persist longer in the market.
You will develop your own strategy over time, because taking one of the already available ones is pointless, it will not work, because a large number of traders have access to it. Trading is a difficult job, and before you find one strategy that will work for you, it may take a very long time, so you also need to have persistence before you can start earning and find your strategy. Personally, trading was very tiring for me compared to my main job, I could not relax and constantly monitored the charts, so in the end I preferred holding instead of trading.
