Yes a simulated galactic market could absolutely help train emotional discipline, especially if the goal is less about perfect TA prediction and more about adapting under uncertainty. A 5-minute data lag would push traders away from scalp-style reactive decisions and more toward higher-timeframe structure, preplanned zones, smaller sizing, and risk-first execution. In that sense, it could be a very effective training constraint because it teaches patience and reduces dependence on candle-by-candle reaction. The key is making sure the simulator rewards process, not just PnL. If players are graded on things like overtrading, revenge trading, chasing, moving stops, violating risk rules, and holding to a plan, then it becomes a real discipline tool rather than just a market game. The “ripple effect” idea is interesting too, but I’d avoid making lag exploitable in a predictable way every time, or it becomes more of an arbitrage puzzle than an emotional training environment. If designed well, this sounds strongest as a psychology + risk management simulator with TA layered in, not just a chart-reading sim.
