Let us create a generator that prints the first 50 natural numbers. If you've noticed that there are two major schools of thought with which you can decide upon When to Buy and When to Sell a Stock, one is Technical Analysis the other is Fundamental Analysis. When the operating system receives certain events, it can pass that to programs in the form of signals. The color of the spectrogram indicates the strength of the signal. Technical Analysis looks upon the price action of the underlying stock or a ticker to identify some patterns, whereas, in fundamental Analysis, metrics such as cash flow, revenue, valuation, or industry trends are being looked upon. I'm creating a class-based signal generator that, given a buy threshold, sell threshold and a list of list of indicators, creates a 'buy' of 'sell' signal on a given day if the indicator from that day is greater than the sell threshold. Now we'll plot for the Buy and Sell signals. The send () method returns the next value yielded by the generator, or raises StopIteration if the generator exits without yielding another value.
