How do you set a macro on bluestacks to harvest everyday?

What I did is maintaining the farms with macros. I have a few farms and it do the upgrades what the farm has. When the macro has finished with a farm change to the next one and do the same. It collects daily rewards and mail rewards. It has errors of course but it works. What I need to implement to build new buildings if it is available but I think it is just an extra feature woul dbe 😃.
