Price Action Trading (P.A.T.) is the discipline of making all of your trading decisions from a "naked" price action chart. This means no lagging indicators. All financial markets generate data about the movement of the price of a market over varying periods of time; this data is displayed on price charts.
While some people choose to buy a position and hold it, called long-term investing, others tend to trade their stocks daily and square off their positions every few days. This is known as short-term trading.
Inflation is a term which you must often hear on the news, debates, and mostly whenever the topic of the economy comes up. Although inflation is mostly discussed in the context of cost of living, it is not just limited to that.
