limit order (rather than fractional) are key to tCost mgmt.

I frequently felt self-hate because the time cost is too high for the small trades. Then I found the concept of recreational stock-picking as the self-defense.

Q: what dollar amount of invested (each week) would relieve the self-hate? $1k/week is too big.
A: $100/week

I think this question is slightly similar to the yoga roti issue in Bayonne. Basically, I felt very good about my yoga lessons, but I also felt self-hate about the 3H total tcost including a leisurely shopping down-time after the yoga, almost as a reward.

— cf: property investment. I tend to spend a few days and commit 5-figure sums (around $100k). Then I execute the deal and put it aside. Therefore, ROTI is very high, but not recreational.
