Help Me my EA won't work

I use Expert Advisor Builder to build my ea. I pick indicator Bolinger Band only. (you can see the website below)

The rule is simple just buy when the price hit the lower band, but I tested it and it didn't work. Someone can help me fix the program or tell me what is wrong with this. :(

I tend to use in 1 hour chart. Thank you before

There's a few problems with this EA which stand out.

 

For starters, use NULL rather than "GOLD" then you can use the EA in any market.

 

There's entry logic for a Buy (where Order = SIGNAL_BUY), however no entry code for a Sell.

 

Also, there's exit logic for a Buy (where Order = SIGNAL_CLOSEBUY) , but no exit code for a Sell.

 

I've not checked the actual entry and exit logic which exists for Buy trades, though I expect it will need some tweaking as (Current + 0) is being used which means that we're looking at the current candle which hasn't closed yet.

 

The best logic will be something like:

 

If candle(Current+2) closed below the lower BB (Current+2) and candle(Current+1) closed above the lower BB(Current+1) then Buy.

 

If candle(Current+2) closed above the upper BB (Current+2) and candle(Current+1) closed below the upper BB(Current+1) then Sell.

 

Price will sometimes make it to the opposite Bolli band, however not always - so you may need to work on exit criteria too. Aiming for the middle band may be better.

I see, thanx soundfx. I still learn the logic as well, and try to build the simple EA. Actually I don't set sell code yet, maybe after this one work I'll set. Thank you very much.
