Vdub Fx SnipperVX3

I copied and pasted a coding strategy from www.tradingview.com. I fix all the corrections in the coding when making it as an expert advisor. When I compiled the file, there were two errors, 2 errors which I don't know how to fix but if an expert can do it then it won't take him 2 seconds. Please help me get this file completed and ready to be used by millions of traders like me. It will also benefit you also. It's only two errors I'm sure it won't take long. The two errors are:

 'len' - declaration without type Vdub FX SniperVX3 .mq4 15 1

 ')' - unexpected end of program Vdub FX SniperVX3 .mq4 132 42

That's the only two errors, and it's annoying me I can't fix it. Please if anyone can fix it and send it back to me so I can install it and see how it works and also put it out for everyone. Thank you so much, pease e-mail me if any questions kevinmanrriquee@gmail.com, I respond very quickly to emails. Thank you so much, everyone!

 The person that created this amazing strategy is Vdubus and his website is www.vdubus.co.uk, he's an amazing guy but I couldn't reach him because I'm sure he has a very busy 

The one I made and try to fix is in the bottom attached, just need to download it and open it. But the original coding will be under here:
