So again i'm used to Crypto Currencies, and since im stupid i learn most things from threads from /biz/ (fortunately i still take decisions based on myself), i've seen plenty on lingo like a bull means a person who bought shares and is intending to sell them at a higher price or someone who has a long option(or a call), a bear is someone who borrowed someones shares sold them immediately and is intending to buy them back again for a lower price receiving the difference meaning a short(or a put).
But how does one make money from the market not fluctuating a lot, or ending up in the same value as bought assuming this is what they refer by "crab market". Is it buying at a certain low point and then selling at a high point and repeating it multiple times and if so how can this be done automatically without constantly setting new lines? what if the stock literally doesn't fluctuate: ie there's no offers on the stock and theres no transactions or trading
