First bands EA version

I wrote the channel based expert advisor using the Bolinger bands indicator as the channel. The first results were good in one week and still the same problem. It's not robust.
The idea works in one week, and in the next it fails.
I changed my trading idea and played with it using the Bolinger bands as the channel itself.
I performed a back test of 25 days and it looks good.

Pros:

• High profit factor - 3.66

Cons:

• Low volume - around 3 days per day

TODO:

• Add money management (right now it trades with a fixed amount of lots per trade)
• Think of a smarter target picking (right now it's fixed take profit)
• Test it with other periods - robustness check
• Try lower time frames
• Optimizations
