Setting up Alpaca API for algorithmic trading

What I am doing is bypassing the interface to be able to place transactions by using code. If you just need to trade, there is no need to use code at all. In fact, it is likely going to be more complicated. However, if you need to make hundreds of microtransactions per day based on indicators that change every few seconds, then you are not trading normally, you are doing quantitative trading. In this account, I will set up a simulation.
