I can't say that this is definitely true. There are strategies that do not change over time, for example, buy low - sell high, all you need with this strategy is patience and the right choice of entry points.
However, the market is developing, and in the short term it can act in an extremely unpredictable manner, which opens up additional opportunities.
The structure has changed in strategy, as thousands of house projects have been built over the years, looking at the drawing may not be different but the old texture exists only in a few important points, the rest will apply advanced techniques and methods, this can also be applied to buy low and sell high strategies, which may only revolve around the trader's virtues and entry points but invisibly have new approaches and new goals. The market is already unpredictable, the strategy can't just boast about the old theory, it is necessary to apply even the smallest changes.
