These plugins cannot be completely relied to be just put in cloud engine google/ amazon. Just replied you in other thread. These are generally windows automation scripts.
If you want a pure algorithmic system you should go for interactive brokers they give an api which is more reliable and free. Write the code from amibroker to interactive broker api. Then put it in google / amazon.
Note IB api can be used only for futures/options not for stocks. If you are trading futures dont think of anything else.
