Ordersend command help?

Hello guys,

I've read through the docs on mql4 on the order send but for some reason my order is not being put through because Im guessing the criteria is never met as no errors appear in the journal.

Do any of you guys see what could be wrong with my code?


Code:
if (OrdersTotal() ==0 && sPatternType == "Butterfly" && Ask > RectanglePriceMax && Ask < RectanglePriceMin)
{
OrderSend(Symbol(),OP_BUYLIMIT,1,RectanglePriceMin,3,RectanglePriceMax,RectanglePriceMin +50*Point,"Order Sent", 16384,0,Green);
Print("Recmax:", RectanglePriceMax, "Recmin:", RectanglePriceMin, "This is for the bullish pattern");

}

most likely the error isn't in the ordersend function but in your logic within the IF statement. If you had any orders already open it will not execute also the logic behind the price min and price max looks backwards, how are the actual values of the rectangle being determined?

Hello! Thanks, you were right, it wasn't even going into the if statement.. I've corrected that, but now im getting this error with the ordersend:


4107

which on the mql site says:
ERR_INVALID_PRICE_PARAM Invalid price.


So is this the entry price they are talking about? the stop price? target profit price?


Thanks!

It may be that the numbers coming back from the rectangle have more digits than the normal price. Try doing this:

NormalizeDouble(whatevervariable,Digits);

This will insure that the price you are sending to the server has the correct digits after the decimal place.

put this in your order condition "Ask - RectanglePriceMin > 10*point"

Thanks guys, its great help as you can tell im obviously new at mql and trying to wrap my head around things...

if you don't mind me asking...

When placing long positions you "Bid", and when placing short positions you "Ask" when using the ordersend? or did i get that mixed up?

or..

Code:
if (OrdersTotal() ==0 && sPatternType == "Butterfly" && Ask > RectanglePriceMax && Ask < RectanglePriceMin)
{
OrderSend(Symbol(),OP_BUYLIMIT,1,RectanglePriceMin-50*point,0,RectanglePriceMax ,RectanglePriceMin +50*Point,"Order Sent", 16384,0,Green);
Print("Recmax:", RectanglePriceMax, "Recmin:", RectanglePriceMin, "This is for the bullish pattern");

}

no need slippage 3 for do pending...
which price you want to make order ->RectanglePriceMin or RectanglePriceMin-50*point

Hi

My question does not directly connect to the forum, but I am a "newbe" and cannot start my own posts.

My question is in OrderSend, how to I set the slippage to the minimum? Can I set slippage to 0? Is there a formula to calculate minimum if there is a minimum? I need to set it in EURUSD

My slippage and values are currently:
orderType[1]
volume[1.00000000]
prefferedPrice[1.31183000]
currentPrice[1.31131000]
requestSlip[131150.00000000pts >> 1.31150000]
currentSlip[-0.00052000]
appliedSlip [1.31202000 >> 13120pts]
takeProfit [1.31030000]
stopLoss[1.31350000]


The reason I ask this is my slippage sometimes is massive, which drastically effects my automated system.

In OrderSend() you can indeed set Slippage to 0, note that slippage is an int and is the number of points of slippage that you will accept . . . except that with some Brokers they seem to take no notice of your slippage parameter or of your open price . . . see this thread: http://www.forexfactory.com/showthread.php?t=416480

You need to know whether you are getting Instant Execution or Market Execution.

Instant Execution (Dealing desk)

  1. You specify price and slippage for market orders. The position will be opened at the current price and only if the current price lies within the range of price+-slippage.
  2. You can specify stoploss and takeprofit in OrderSend().

Market Execution (STP/ECN)

  1. Market orders will be opened at the best available price, which can be ANY price. Hence the price and slippage parameters are ignored.
  2. You can't specify stoploss and takeprofit for market orders in OrderSend().
  3. The only way to prevent slippage is to use limit orders instead.

I am sure you are correct . . . unfortunately this contradicts what is written in the documentation for Ordersend()

"At opening of a market order (OP_SELL or OP_BUY), only the latest prices of Bid (for selling) or Ask (for buying) can be used as open price. If operation is performed with a security differing from the current one, the MarketInfo() function must be used with MODE_BID or MODE_ASK parameter for the latest quotes for this security to be obtained. "

I can't find any Metaquotes documentation for Market Execution, even though it's been around for years.

Yep, I'm trying to talk to Metaquotes about this but it's currently a one way conversation.
