There are many traders who make big money using "basic" tools (price, moving averages, standard momentum indicators, etc.).
More complexity often means more noise, which complicates building a strategy that you can realistically implement in the market.
Excessive complexity also creates a tracking problem. It's much easier to reconcile 1-2 conflicting signals than 4-5 signals saying different things.
In most cases, we try to broadly capture similar market effects (trend, momentum, mean reversion, delta imbalance, etc.) - there are no extra goodies for getting the same answer through more complex work.
Start with simple things you know well and iterate slowly (if necessary).
Complexity and new variables should be added as needed and with the minimum effective dose.
A trader using a moving average with simple entry/exit criteria will find it easier to refine their system than a trader simultaneously looking at OI, funding, quarterly futures basis, CVD, liquidity heatmaps, etc., trying to synthesize a unified, coherent trading idea."
