AN EA BASED ON B BANDS AND B WIDTH, NEED SOME URGENT HELP !!

[surubabs Suresh Kakkattil]

Dear All,

I am programing an ea which works with B Band And B Width, For the B Width I have added a custom EA, There is No Error Comeps when i compile,

But i am shure there some probs in Custom Indicator calling .

so i need some programers help to correct it, i allways to be thankfull who helps me this time, bcoz i got stoped now,

But i am shure there some probs in Custom Indicator calling .

so i need some programers help to correct it, i allways to be thankfull who helps me this time, bcoz i got stoped now,

Thanks In Advance 

Please give attention on order of input parameter of iBand Widh :

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",ibands_period,ibands_shift,ideviation,PRICE_CLOSE);

According to input order of indicator, it should :

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",ibands_period,ideviation,iapplied_price,ibands_shift);

[graziani]

you don't need this custom indicator.

you have bbands, just subtract the envelopes of bbands.

As I said before you should pay attention to  the orders. So if input parameter like this :

input uint bands_period=20; //smoothing depth                    
input double deviation=2.0; //deviation
input ENUM_APPLIED_PRICE  applied_price=PRICE_CLOSE; //type of price or handle
input int Shift=0; //horizontal shift of the indicator in bar

then to call indicators you should write the same orders

BB_Handle=iCustom(NULL,PERIOD_M1,"i-BB-Width",bands_period,deviation,applied_price,Shift);

As I said before you should pay attention to  the orders. So if input parameter like this :

then to call indicators you should write the same orders

I did it like u advaiced, but the problem i am still facing is in ontick(), when i copy the buffers, the width indicator only has a single line, and in the indicator code it shows as IndiBuffer,

Then which buffer should i copy from the width indicator, if it is like in the widthindicator code . 

//---- copy newly appeared data into the arrays  
   if(CopyBuffer(BB_Handle,UPPER_BAND,0,to_copy,UpBB)<=0) return(RESET);
   if(CopyBuffer(BB_Handle,LOWER_BAND,0,to_copy,DnBB)<=0) return(RESET);

i cannot use this in buy sell conditions,

please advice me to program it in the correct way, i tryed more than two whole days on this,

Please help sir.

What graziani said to you is that use of "i-BB_Width" is unnecessary. This indicator only calculate the difference between Upper and Lower bands. So you can completely remove this indicator from your EA.

After that it's up to you to check the logic of your algorithm.

Ha ha nice solution, i like it :-)

Sir,i have a dought,

can i dife the width in an ea ? like width=Upband-Lowband/Baseline,

is it posible ?

Sorry but I don't understand your question.

Sorry some spelling mistake,

i want the width of the band for this it need some calculation like

Width=(upperband-lowerband)/baseband

so is it possible to do this calculation inside the ea ?

how to define this ? when i tryed getting an error,

Width[]=(Upperband[ ]-Lowerband[ ])/Baseband[ ],

please advaice
