Relationship between volume and Liquidity-
A large volume spike proceeds a trend reversal (a giant red volume bar on the daily chart likely indicates seller exhaustion and indicates a reversal, the inverse is true for a large green volume bar equalling buyer exhaustion).
Shares Outstanding- Total number of shares
Share Float- Shares available on the open market (not held by insiders or borrowed on margin by short sellers) I target low float stocks with high short interest... short squeeze!
Short Interest- The ratio of shares outstanding that are held by short-sellers
Volume-
The number of shares traded per day measured by dollar amount. Reference the float to see if the volume is worthy for a trade. No volume + Low liquidity= getting stuck in a trade that doesn't move and is nearly impossible to exit. Noobs learn this within their first few months (in most cases).
Blow off tops and bottoms-
Blow offs are a chart pattern that shows a steep and rapid increase in a security's price and trading volume, normally outside of a predictive chart pattern followed by a steep and rapid drop in price usually on significant or high volume as well.
I call the final accelerated push an impulse wave. Impulse waves are fueled by retail greed and FOMO causing a hyper-accelerated rise in asset prices. Smart money uses this influx of cash (liquidity) as funding to exit the trade with a huge profit with the help of high-frequency trade machines. This liquidity event is also used to burn retail long and shorts in a flash crash manner in both directions before the predicted trend change occurs at the blowoff top or bottom. The traders are usually right about their trend prediction but impulse waves are designed to destroy margin traders on both sides of the trade before resuming the trend. Blow off tops usually happen in a single asset, do all of what I described above, and print the giant volume bar, as I mentioned above in the Relationship between volume and Liquidity. Blow off tops in single assets that resemble a bubble and illogical price action often signal a market-wide top and trend change in the current overall trend. (I'm predicting that TSLA is going to be the blow-off top that signals the market-wide topping out of this bear rally followed by resuming the course of bear market selling.)

I don't trade with margin or anything that requires borrowing in any capacity. This includes leveraged buying, selling short or leveraged short positions, options, futures or anything leveraged. This is my personal preference, I am not downplaying these products as many people see success with them. Self-awareness is important. I know what I'm good at, what I'm bad at, and what compromises my success. Margin is the enemy of my success... and it's way too stressful babysitting positions!
