usage: load [-t TICKER] [-s START] [-e END] [-i {1,5,15,30,60}] [--source {yf,av,iex}] [-p] [-r {ytd,1y,2y,5y,6m}] [-h]

Load a symbol to perform analysis using the string above as a template. Optional arguments and their descriptions are listed below. 

The default source is, yFinance (https://pypi.org/project/yfinance/). Alternatively, one may select either AlphaVantage (https://www.alphavantage.co/documentation/) or IEX Cloud (https://iexcloud.io/docs/api/) as the data source for the analysis. Please note that certain analytical features are exclusive to the source. 

To load a symbol from an exchange outside of the NYSE/NASDAQ default, use yFinance as the source and add the corresponding exchange to the end of the symbol. i.e. 'BNS.TO'. 

BNS is a dual-listed stock, there are separate options chains and order books for each listing. Opportunities for arbitrage may arise from momentary pricing discrepancies between listings with a dynamic exchange rate as a second order opportunity in ForEx spreads.

Certain analytical features, such as VWAP, require the ticker to be loaded as intraday using the '-i x' argument. When encountering this error, simply reload the symbol using the interval argument. i.e. 'load -t BNS -s YYYY-MM-DD -i 1 -p' loads one-minute intervals, including Pre/After Market data, using the default source, yFinance. 

Certain features, such as the Prediction menu, require the symbol to be loaded as daily and not intraday.
