any difference????
IMHO there shouldn't be any difference, unless there is a difference in execution time of both approaches. Possibly a good idea would be to create 2 separate functions, loop each of them e.g. a 100 times in the script and run it in the profiler to see the execution time. If such test proves that there really is a difference in execution time, I'd expect #2 to be slightly faster.
When you go to the documentation page for 'ENUM_SYMBOL_INFO_DOUBLE', and look at the description for 'SYMBOL_BID', it says that it gives the best sell offer.
What the hell does 'best' mean, are there more than one bid offers? Confused.... :-(

It just refers to current prices at the market. Probably the phrasing of this description is a little bit unfortunate. However, nothing to do with MQL5 itself.

I'm just wondering if there is any difference between the two lines of code below.... (for calculating the spread)
1:
double Spread_1=NormalizeDouble(SymbolInfoDouble(Symbol(),SYMBOL_ASK) - SymbolInfoDouble(Symbol(),SYMBOL_BID),_Digits);

2:
MqlTick current_price;
double Spread_2=NormalizeDouble((current_price.ask-current_price.bid),_Digits);
