Script / Function - Last Candle = buy candle or sell candle .

[Nicolas Raffin]

Hi everyone.

I don't know how to express my problem.

I managed to get the value of the last candle called LastCandleNb.

if it is >0 then bullish candle.

if <0 then bearish candle.

I can do it live.

if(LastCandleNb>0)

      Comment("Buy Candle");

   else

      Comment("Sell Candle");

But I would like to improve the function. to call it in the code more easily. like. (and make it a .mqh, if possible)

LastCandle = bullish candle or bearish candle

of course, depending on LastCandleNb < or > 0.

I just have to do

comment(LastCandle);

But impossible to find a formulation without error.

Thanks a lot.

Before you get any answer, you have to inform us about the  LastCandleNb ?

what you mean by that " LastCandleNb "? is it a fixed variable, runtime value or a function which return a number... ?

otherwise, no one can understand what you want!

Adding screenshot(s) could help reader to give a good answer

Hello,

thank you Mohammed for your answer!

Yes of course, sorry, I hadn't thought about it

i use:

#define LastCandleNb iClose(_Symbol,PERIOD_CURRENT,1)-iOpen(_Symbol,PERIOD_CURRENT,1)

so I get a positive or negative value.

but this is probably not the right method, or the simplest one

Hello you can define the candle number in the definition as well :

#define LastCandleNB(int) ((iClose(_Symbol,_Period,int)-iOpen(_Symbol,_Period,int))/_Point)>0.0?1:-1
/*
explanation
if the Close minus the Open at int location is bigger than 0 then return 1 otherwise -1
*/

double  LastCandleNb= iClose(_Symbol,PERIOD_CURRENT,1)-iOpen(_Symbol,PERIOD_CURRENT,1);

Hello Lorentzos,

thank for your answers.

I didn't really understand why, but it's a great update! more clear..

Now, i have :

LastCandleNb = 1 or -1

But, can you direct me to,

I would like to have

LastCandle = BuyCandle / or / SellCandle.

in fact I want to call directly in my ea.

Comment(LastCandle)

and that it shows me

BuyCandle or SellCandle

 but I don't see how to have LastCandle with 2 possibilities.

thank you all for your help

You can return a string in the ternary operator too , like this : 

#define LastCandleNB(int) (iClose(_Symbol,_Period,int)>=iOpen(_Symbol,_Period,int))?"BuyCandle":"SellCandle"

It checks is the Close >= Open ? if yes return BuyCandle if not return SellCandle
