tim.ye: so I am not sure why the bid is displaying 0.7008799999999999.
You used NormalizeDouble, It's use is usually wrong, as it is in your case. - Floating point has infinite number of decimals, it's your not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)
Double-precision floating-point format - Wikipedia, the free encyclopedia - Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.
- SL/TP (stops) need to be normalized to tick size (not Point) — code fails on metals. (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 programming forum) and abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum
- Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on Metals. So do it right: Trailing Bar Entry EA - MQL4 programming forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 programming forum
- Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.
- MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

How to Normalize - Expert Advisors and Automated Trading - MQL5 programming forum - Prices you get from the terminal are already normalized.
- PIP, Point, or Tick are all different in general.

Hi there,
I am new to this so would appreciate any help I can get. I have the following code to display the bid, ask and spread.
It is displaying the bid correctly except for a couple of pairs (CAD/CHF and NZD/JPY). I've done troubleshooting and digits is 5 for CAD/CHF so I am not sure why the bid is displaying 0.7008799999999999.
int digits=(int)MarketInfo(symbolName,MODE_DIGITS);
double vAsk=NormalizeDouble(MarketInfo(symbolName,MODE_ASK),digits);
double vSpread=NormalizeDouble(MarketInfo(symbolName,MODE_SPREAD),digits);
string tooltip=symbolName+"\n.: Price :.\nAsk: "+(string)vAsk+"\nBid: "+(string)vBid+"\nSpread: "+(string)vSpread;
DrawLabel("price_"+symbolName,x,y,(string)vBid,fontSize,fontName,clrWhite,tooltip);
Appreciate your help in advance.
Thanks!
