Block builders, bundle things like that, retail investors actually don't need to study enough to write code.

Just remember one thing: the moment you click "buy/sell," it doesn't necessarily go on the chain immediately.
In the middle, you'll be watched by a bunch of people queuing, cutting in line, or even squeezed in the middle to make some profit (like sudden slippage).
So I personally think the sufficient level is: don't use outrageous slippage, don't chase the newly emerged candlesticks, don't squeeze into pools where many are competing.
If you really want to rush, do small amounts, split orders, and set acceptable failure losses.

Recently, Meme and celebrity call signals are moving too fast, basically it's a relay race of attention.
Veterans advise newcomers not to take the last step—that's not pretentious.
You see the excitement, but in fact, many trades are packaged together and shoved in.
All you can do is not let yourself become "the well-packaged one"...
Anyway, I now prefer to miss out rather than keep paying tuition.
