Return the value of a digit

New comment
 

I need to get the actual pip value of a digit after a decimal place. Is there a function I need to use?

 
points=price - MathFloor(price);

Amazing how two people interpret the question in a totally different way! I thought he was looking for the fraction part - go figure.

I don't know what he wants.

  1. The fractional part is not a 'pip value' The entire price (except for the extra 3/5 digit) is.
  2. 'a digit' is not a 'pip value'
 

Sorry for the confusion, what I am actually hoping to find out is when the price (Bid) value crosses over the 500 or 000 in a currency.

For example: GBP/USD is at 1.56352 and crosses above 1.56500 or below 1.56000

In summary, I am only wanting to track the last 3 digits

The price of GBPUSD can't be at 1.56352 AND be above 1.5650 or below 1.5600 . . . at some point you need to remember the 1.56352 figure . .

So something like . . .

double RememberedBid;

if( ( Bid * 100 ) > MathFloor( RememberedBid * 100 ) + 0.5 )   // above 1.56500

if( ( Bid * 100 ) < MathFloor( RememberedBid * 100 )  )        // below 1.56000
 

Hi 7640,

You have to create UDF for that, an UDF to extract last 3 digits. Use DoubleToString(), StringTrimLeft(), and back to StrToDouble() (Those are links, please click)

That's what I can think of.

 

GBP/USD is at 1.56352

To get value 1.56000 or 1.56500

double Pipslevels   = 50 * pips2dbl;     //50 pips   pips2dbl correction 4/5 digit brokers define it ..... way of WHRoeder



//Level Lower Bid  1.56000

double LowerValue = MathFloor( Bid / Pipslevels) * Pipslevels;


//Level Higher Bid  1.56500

double HigherValue = MathCeil( Bid / Pipslevels) * Pipslevels;

Think this is the way.... am i correct ??
