Error Order Send 138.

Maybe some refs below sort you out...

A. Terminal Help: Managing of Trade Positions — Placing of Pending Orders

B. Terminal Help: Trading -- Order Types

B. Editor Help: Standard constants - Trade operations

C. Editor Help: Trading functions - OrderSend

D. Not forgetting THE BOOK... see top of topics list

1. are you using one of:

MQL4 Reference - Standard constants - Trade operations

OP_BUYLIMIT	2	Buy limit pending position.
OP_SELLLIMIT	3	Sell limit pending position.
OP_BUYSTOP	4	Buy stop pending position.
OP_SELLSTOP	5	Sell stop pending position.

2. using: Ask [+/-] N*Point ?

must be normalized (via Point)

3. what SLIPPAGE using ?

Please show code - unknown how you calculate OrderSend() inputs, unknown OrderSend() call....

For Now, thanks you a lot!

I'd use a slippage of 3

I use Ask-(NormalizeDouble(20*Point),2)

I didn't refer to the right trade operation code...

After that. I need/It would be better to refresh quotes in a loop?

Thanks

may I point out syntax issue - see above - compiler would shout but....

I trust below does not offend - but seems that some background may be of interest (hahaaa, always helps me get things better in head if go through examples etc. :)

Long time ago I made function to dump MarketInfo() - if no actual param then use Symbol()

I made function to help me 'see' all marketInfo data for a symbol pair - I've got to see else just not make sense...

Please notice colored lines in the logged marketInfo Print()'s at end.

Reason I did this is your code produces double value rounded to fixed two decimal point digit precision, yes?

ref: MQL4 Reference - Conversion functions - NormalizeDouble

IF did this for let's say, gbpusd which has 4 decimal point digits the result would be

eg, let gbpusd/Ask = 1.9812 and Point = 0.0001, so using your code:

1.9812 - {(20*0.0001) to two digits} = 1.9812 - {0.0020 to two digits} = 1.9812 - 0.00 = 1.9812

(now, assuming I've got this right :), what really wanted was to four digits: 1.9812 - 0.0020 = 1.9792

If use: Ask - NormalizeDouble(20*Point,MarketInfo("GBPUSD",MODE_DIGITS))

you get eg, 1.1234 and not 1.12

See how the MarketInfo(..) frees code from being specific for just one decimal point precision? (kinda same idea as using #define's instead of constants...)

Consider using:

let: sym = "GBPUSD"; //or whatever symbol EA may be using at that moment (or just use Symbol() instead of sym if only ever using EA's chart symbol pair)

then finally we get: NormalizeDouble(20*Point,MarketInfo(sym,MODE_DIGITS))

which will work for any symbol pair.

MQL4 Reference - Window functions - RefreshRates

Not sure really needed unless computing for long period - the EA gets latest tick data when called.

I believe that this function is best used when you have used Sleep() due to say a retry loop - it could be that Terminal gets 1 or more ticks while EA sleeping and in this case is vital to call refreshRates else ea will not 'see' this latest server data...
