Here is my code:
if (amount != -1)
returnJson.Add("<p style=\"color: black;\">" + double.Parse(res_q.Replace(",", ".")) * amount + " " + res_i + "</p>");
else
returnJson.Add("<p style=\"color: black;\">" + res_q + " " + " ") + res_i + "</p>");
And no matter if the execution of the program goes to if or the else, if res_q="1,5", this returns 15 on server, and 1.5 locally.
Why is this happening?
The problem was in the comma.
I want to apply globalization in my program. Using CultureInfo.InvariantCulture was the answer I needed. Or simple replcing the comma with dot.

I'm trying to extract Search queries by certain rules and I need to get Queries that contain one of the given strings:
" WHERE " +
" Impressions > " + IMPRESSIONS_THRESHOLD +
" AND AverageCpc > " + AVERAGE_CPC_THRESHOLD +
" AND Query CONTAINS_ANY ['for sale in', 'buy'] " +
" DURING YESTERDAY ");
But I'm getting error message (tryed different variations):
One of the conditions in the query is invalid. (file Code.gs, line 19)
Although it seems like I do everything according to Formal Grammar:
String -> StringSingleQ | StringDoubleQ
StringSingleQ -> '(char)'
StringDoubleQ -> "(char)"
StringList -> [ String (, String)* ]
If I do just 1 string it works fine:
" WHERE " +
" Impressions > " + IMPRESSIONS_THRESHOLD +
" AND AverageCpc > " + AVERAGE_CPC_THRESHOLD +
" AND Query CONTAINS 'for sale in' " +
" DURING YESTERDAY ");
IIRC, the CONTAINS_ANY operator only works when you are filtering on labels. I'm not sure if this constraint is actually documented, but this article seems to at least imply it.
I would like to fire a function as soon as a trade was closed (= the OrdersHistoryTotal increased by at least 1).
Is there any handler in MQL4 for such scenarios?
In my particular setup I have the following function pushSocket which should only push data in case the OrdersHistoryTotal changed.
int i,hstTotal=OrdersHistoryTotal();
string historical_trades = "";
for(i=0;i<hstTotal;i++)
{
if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)==false) continue;
historical_trades = historical_trades +
"historical_trades|" +
version + "|" +
DID + "|" +
AccountNumber() + "|" +
IntegerToString(OrderTicket()) + "," +
TimeToString(OrderOpenTime(), TIME_DATE|TIME_SECONDS) + "," +
TimeToString(OrderCloseTime(), TIME_DATE|TIME_SECONDS) + "," +
IntegerToString(OrderType()) + "," +
DoubleToString(OrderLots(),2) + "," +
OrderSymbol() + "," +
DoubleToString(OrderOpenPrice(),5) + "," +
DoubleToString(OrderClosePrice(),5) + "," +
DoubleToString(OrderStopLoss(),5) + "," +
DoubleToString(OrderTakeProfit(),5) + "," +
DoubleToString(OrderCommission(),2) + "," +
DoubleToString(OrderSwap(),2) + "," +
DoubleToString(OrderProfit(),2) + "," +
"<" + OrderComment() + ">|";
}
pushSocket.send(StringFormat("%s", historical_trades, true));
I tried to insert a counter to compare it but the counter is deleted every time on memory clean-up.. The above function is nested in a onTick function which executes every second.
There is a function OnTradeAction() in MQL5 that is called every time some trading action is done. But unfortunately this function is not available in MQL4. On the other hand, you can implement a function inside OnTick() that will check that HistoryTraderTotal() increased compared to the previously saved value, and do all the steps you like in that case. A bit more work but almost the same.
OnTimer(){
Mt4OnTradeAction();
otherLogic();
}
Mt4OnTradeAction(){
static int historyTradesTotal=0;
if(HistoryTradesTotal()==historyTradesTotal) return;
historyTradesTotal = HistoryTradesTotal();
processingTrade();
}
I am searching for a solution to just and only consider real forex pairs in my loop. I don't want CFDs, commodities, silver, gold, etc. to be included because they have a complete different logic when it comes to calculating pips etc. etc. (I want to use the data for a FX dashboard).
How can I implement a filter to do so without building if-statements for every FX pair existing?
If possible, the solution should be independent of the broker used (since the offered FX pairs might be different from broker to broker, so a common approach would be the all-in solution).
This is my current code that doesn't seperate between fx and non fx:
/*
2.) Create a string format for each pending and running trade
*/
int live_orders = OrdersTotal();
string live_trades = "";
for(int i=live_orders; i >= 0; i--)
{
if(OrderSelect(i,SELECT_BY_POS)==false) continue;
live_trades = live_trades +
"live_trades|" +
version + "|" +
DID + "|" +
AccountNumber() + "|" +
IntegerToString(OrderTicket()) + "|" +
TimeToString(OrderOpenTime(), TIME_DATE|TIME_SECONDS) + "|" +
TimeToString(OrderCloseTime(), TIME_DATE|TIME_SECONDS) + "|" +
IntegerToString(OrderType()) + "|" +
DoubleToString(OrderLots(),2) + "|" +
OrderSymbol() + "|" +
DoubleToString(OrderOpenPrice(),5) + "|" +
DoubleToString(OrderClosePrice(),5) + "|" +
DoubleToString(OrderStopLoss(),5) + "|" +
DoubleToString(OrderTakeProfit(),5) + "|" +
DoubleToString(OrderCommission(),2) + "|" +
DoubleToString(OrderSwap(),2) + "|" +
DoubleToString(OrderProfit(),2) + "|" +
"<" + OrderComment() + ">|";
}
This is probably the easiest way. Prefix symbols might be a problem (e.g. mEURUSD) but easily solved by shifting the StringSubstr values by the prefix size. Suffix is not a problem as we take the first 6 chars of the symbol string.
const string FX_CURRENCIES[]={"EUR","GBP","USD","NZD","AUD","CHF","CAD","JPY"};//add other currencies if needed
bool isFxPair(const string symbol){
return StringLen(symbol)>=6 && getCurrencyIdx(StringSubStr(symbol,0,3))>=0 &&
getCurrencyIdx(StringSubStr(symbol,3,3))>=0;
}
int getCurrencyIdx(const string smb){
for(int i=ArraySize(FX_CURRENCIES)-1;i>=0;i--){
if(FX_CURRENCIES[i]==smb)
return i;
}
return -1;
}
Use of CStringArray and caching FX symbols might be another good idea that may potentially work faster, but it seems to use the similar logic as above(but you'll have to sort the cache every time you add something in order to have CStringArray collection to work fast).
There is no direct method to ask whether a symbol is FX, CFD, Stock, Crypto or anything else.
I am using the HDF5DotNet with C# and I can read only full data as the attached image in the dataset.
The hdf5 file is too big, up to nearly 1.4GB, and if I load the whole array into the memory then it will be out of memory.
I would like to read all data from One columns
double[] values = new double[203572];
string m_Doc_01 = "data/sample/line";
HDFql.Execute("USE DIRECTORY " + "\"" + File_Directory + "\"");
HDFql.Execute("USE FILE " + "\"" + File_Name + "\"");
HDFql.Execute("CREATE CHUNKED(1, 203572) DATASET my_dataset_BS AS DOUBLE(2050, 203572)");
How to "m_Doc_01 ==> my_dataset_BS" Data
???
???
for (int i = 0; i < 2050; i++)
{
HDFql.Execute("SELECT FROM " + "\"" + m_Doc_01 + "\"" + "(1:::1) INTO MEMORY " + HDFql.VariableRegister(values));
}
To read the column that you have highlighted in the screenshot (i.e. column #0), you have to change the hyperslab to (please note the 0):
HDFql.Execute("SELECT FROM " + "\"" + m_Doc_01 + "\"" + "(, 0:::1) INTO MEMORY " + HDFql.VariableRegister(values));
That said, if you want to loop through the dataset and read one column at the time do the following (also better to register variable values before the loop starts and unregister it after the loop is done - this will increase performance):
number = HDFql.VariableRegister(values);
for(int i = 0; i < 2050; i++)
{
HDFql.Execute("SELECT FROM " + "\"" + m_Doc_01 + "\"" + "(, " + i + ":::1) INTO MEMORY " + number);
// do something with variable "values" (which contains the values of column #i)
}
HDFql.VariableUnregister(values);
I am trying to use Google Adwords Reporting HTTP POST request to retrieve stats for a list of keywords that could exist under multiple Campaigns/Adgroups. This is the API documentation that I was referring to https://developers.google.com/adwords/api/docs/guides/reporting#prepare-the-http-post-request.
Below is scala code that returns 400 error code. What am I doing wrong ? Or is there another way of retrieving data from KEYWORDS_PERFORMANCE_REPORT report type ?

val httpResponse=httpClient.execute(postRequest)
println(httpResponse.getStatusLine.toString)
Your report definition should go into the POST request's body encoded either as application/x-www-form-urlencoded or multipart/form-data—in your code you are adding it as a header called Parameters.
