HTTPS Access

Key HTTPS Access in ExCfgLvFdMS refers to a boolean that controls the URL that should be used for the Marketstack
TRUE refers to an encrypted url starting with https, which provides enhanced security that the received feeds have not been tampered with by external actors.
FALSE refers to an unencrypted url starting with http
The default is FALSE because Marketstack grants access to https only under the free plan.
Therefore, if your code entered in API_Key corresponds to a paid plan, you will be able to set this flag to TRUE for enhanced data security.
