A very bad model that lacks accuracy and precision, yes. Maybe if you're a PhD quant at Citadel then you can create a very small statistical edge when gambling on an economic system. There's no analytic solution to complex economic systems in practice. It's just noise and various ways of validating efficient market hypothesis.

Also, because of heteroskedasticity and volatility clustering, using time-based bars (e.g. change over a fixed interval of time) is not ideal in modeling. Sampling with entropy bars like volume imbalance bars, instead of time bars, gives you superior statistical properties, since information arrives in the market at irregular times. Sampling by time is never the best way to simulate/gamble on a market. Information is the casual variable, not time. Some periods of time have very little information relative to other periods of time. In modeling, you want to smooth out information independently of time.
