A suggestion for you:
What o/p do you prefer? above or below... (sure I did log copy then had to add newlines but nevertheless... ;)
It is easy to confuse self much by having ones eyes bounce left/right continuously from text/output
Errors easily made.
.
1. Why does it show Point as 0 ?
Read Print() docs again please. You will notice Print's default o/p width is ???
This 'issue' has come about due to 3,5 subpip pricing by some Brokers. Print() is pre... so 4 digits was ok...
of course norm'ing point is pointless! just did it for heck of it...
Please study DoubleToStr() for resolution - this catches out many and is massive headache until realize!
.
2. BID + SPREAD * POINT = ASK --- IS THIS CORRECT AT ALL ?
your answers will change IF you program generically.
.
3. How do we write generic code that fits across currency pairs based on above predefined variables ?
Suggest you do not assume symbol/broker values ie, SPREAD.
Use MarketInfo() - is what it's for, and that is also good clue to HowTo deal with generics...

This is wrong on a 5 digit broker. What was meant was 30 pips. It should have printed 0.0030 and 1.4065 or
It should have printed 0.00300 and 1.40650.
double pips2dbl = Point, pips2points=1;
if (Digits == 3 || Digits == 5) {pips2dbl *= 10.0; pips2points*=10;}
// NormalizeDouble(30*pips2dbl,Digits) should print 0.00300 (30 pips)
// NormalizeDouble(Bid+30*pips2dbl,Digits) should print 1.4065 (bid + 30 pips)
pips2dbl is used as max_spread
OrderClose(ticket, OrderLots(), Ask, 3*pips2points, Red);

To understand the POINT, Digits and NormalizeDouble better, I tried to print these values along with Bid and Ask variables.
Print("Point Digits BidPrice AskPrice Bid & AskNormalizedValues POINTnormalizedValue and Bid PLUS POINT*PIPS- ",Point," ",Digits," ",Bid," ",Ask," ",NormalizeDouble(Bid,Digits)," ",NormalizeDouble(Ask,Digits)," ",NormalizeDouble(30*Point,Digits)," ",NormalizeDouble(Bid+30*Point,Digits));

Now My question
1. Why does it show Point as 0 ?
I thought if the SPREAD is a static value of 3 PIPS we will have
2. BID + SPREAD * POINT = ASK --- IS THIS CORRECT AT ALL ?
3. How do we write generic code that fits across currency pairs based on above predefined variables ?
This equation doesn't hold in the above printed example. because although it says DIGITS value is 5 and we know spread value is 3 PIPS but I need to use 30 as a multiplier with POINT because the Bid and Ask are quoted in 4 digits.
