MA Crossover alert Delay

Hi Guys.

I need some help. I have been using the EMA Crossover Signal indicator for crossover alerts in the H1 chart and notice that the alerts are always delayed by 1 bar after the actual cross.

How can i fix this so that the alert rings immediately at the cross without any delay.

My broker's server time is GMT +1. Is this the cause of the problem? If so can someone tell me how i can modify the indicator for this change?

I will deeply appreciate any help. Thank you very much!

The code for the indicator is as fellows
