You can split up your buying and skimming profits over time so your building a position over many months to years and periodically taking profits near the tops and rebuying and increasing position every couple weeks when the market corrects.

Also another great thing to try is get SPX/USD on 500:1 leverage so on a good day when S&P goes up 2% with the leverage multiplier can significantly increase return.

Owning stocks is a good idea. But if you just buy the S&P every month, you probably don't need a "terminal stock watcher and stock position tracker", which is the program being discussed here. It seems like a symptom of a short-term exuberance that may not end well for most participants.
