I placed the EAs over the charts, but no trades are opening

Make sure to enable Auto Trading before placing the EAs over the charts. If you place the EAs and then enable Auto Trading, it might not work.

Also, some beginner traders forget that during the weekend, the Forex market is closed, and you cannot expect trades to open during the weekend hours. 

Another reason could be that your broker does not allow algorithmic trading. Check out the trusty brokers we use for algorithmic trading where EAs trade fluently. 

Also, ensure you have sufficient funds to trade, your leverage is not too high and your lot sizes are not set too high.
