The provided cAlgo code defines a Simple Moving Average (SMA) trading robot. This algorithm uses a specified SMA period to determine whether to execute buy or sell market orders based on the SMA's crossover. If the SMA indicates a sell signal and there are no open positions, it sells; conversely, if it signals a buy and there are no positions, it buys. Additionally, it checks open positions and closes them if the SMA signals a crossover opposite to their initial trade direction.
