Getting spread in MetaTrader 4

[karan]

am using the following to compute the spread in points for the current chart:

string symbol = Symbol(); // Get chart symbol
int spread = MarketInfo(symbol,MODE_SPREAD);

spread is being set to 0. I have verified that symbol is valid (set to "EURUSD").

What is wrong with the above?

For current chart, use this karan:

PHP Code:

int spread = (Ask - Bid) / Point;

I'm not sure but someone suggested this:

PHP Code:

#import "your.dll"
int yourmethod(string& some_string);
#import
