Trading is one of the few things that doesn't get easier the more you do it unless you make the right changes and do certain things and avoid certain things. If you continue to do the same thing over and over and expect a different result you are setting yourself up for disappointment. If you are using simple, widely known and commonly used strategies and methods with very little forethought and effort your results will be breakeven or less. The big players make their profit from those who are less skilled and experienced in this zero sum game. Less skilled and experienced traders all do the same things at the same time and they are part of a group known as the "herd". The "herd" is trading the surface of these markets including stocks, Forex, cryptocurrencies, futures, etc. Changing your "strategy" isn't enough. Changing your broker, platform, etc. will not bring you success. The road to profitability is to take a different path. When the herd is buying as price moves to new highs you want to be out of the market looking for the best place to strategically place your pending sell order, waiting patiently for the market structure to send you a signal that your probability of success is at it's maximum. Ditto on the sell side.
You don't need to spend years learning more technical analysis. The game is about proper execution and order flow not about who knows the most technical analysis. The simpler your system the better. But it has to be used with an advanced understanding of how the trading game is played and what are the best ways to enter and exit the market. You cannot jump into these markets at anytime anywhere in the market structure and expect to make a constant profit. Your active participation will be amply rewarded by trading losses.
You need to condition your mind through repetition and gain the confidence to trade in a way that goes against your inner voice or "gut feeling" to buy at the high and sell at the low. You know from experience that following that inner voice will lead you astray. Start to think outside the box and do things differently and you will probably start to see some improvement in your trading results.
