Retirement Accounts vs. Taxable/Trading Accounts:

Do you diversify and treat your retirement accounts different than your taxable/trading accounts, whereby retirement accounts tend to be more often invested in ETFs (based on high probability chart patterns, etc.), taking larger positions and holding for longer periods?

Not buy & hold, per se, but in general, held relatively longer due to lower volatility, smoother trends with less choppiness due to diversification and less short-term risk vs. individual stocks?
