rock-hard agree with this. i've also found similar benefits from trading in the trenches on a side wallet for fun/experimentation. once you get outside of "i'm buying this boring thing cheap, and i'm gonna sell it at market culmination many months, or potentially a year or three later" sort of "one trade in, one trade out" investing, and you get into trading-trading, there are two things: technical abilities, and harnessing your emotions. doing scalping or trenching aren't going to be a 1:1 overlap with HTF trading or swing trading levels, but they're going to give you an opportunity to do something super valuable: give you enough reps/feedback to learn to control your emotions, largely via getting your teeth kicked in whenever you trade emotionally, rather than calculatedly. the reason many people find trading so hard is because you need to do the *polar opposite* of everything your brain is wired to do. at range highs/resistance, and a natural spot to sell? the untrained mind sees a price that.. needed to pump to get there. no part of our psychology says "oh wow this thing is doing well, i should cut it here" and conversely, something dumps down to support: no part of our mind natively sees something doing poorly, and says "wow this thing is losing and doing bad, i want a piece of this!" unless you're some sort of psychotic robot, the only way to internalize this and action it reliably (against your base emotions) is reps and feedback. getting those reps and feedback both at scale is invaluable toward compartmentalizing base pre-programmed human instinct, even if the patterns between different timeframes and systems is different.
