How to use Time in calculations
I am new to MQL4 and was just trying to see if I could make a simple EA that would use some basic functions. I know C++ well but must be awful at MQL4 because I something is worng with this code and I think it has to do with the time functions or possibably the buy/sell functions, heres the code: ...and by the way this wasnt designed to make money just test the functions Thanks!
int start()
{
//----
double currenttimeN, currentvalue;
double timeM = TimeMinute (TimeCurrent());
double timeH = TimeHour(TimeCurrent());
currenttimeN = (timeH / 24) + (timeM / 1440);//gives the time of day as a percent or 1 (1 = one complete day) so always less than 1
currentvalue = Ask;
if (currentvalue > currenttimeN){
OrderSend(Symbol(),OP_SELL,1,Ask,3,Ask-25*Point,Ask+25*Point,"My order #2",16384,0,Green);
}
/* BUY COMMAND */
else if (currentvalue < currenttimeN){
OrderSend(Symbol(),OP_BUY,1,Ask,3,Ask-25*Point,Ask+25*Point,"My order #2",16384,0,Green);
}
//----
return(0);
}
...................
Wrong string:
could be:
[CODE]currenttimeN = (timeH *60 + timeM) / 1440;How can you compare part of day and price?
buy and sell at the same time
can someone help to program so tat i can buy and sell at the same time...some scripts or etc...
i appreciate it...
example:
if (Stoch1>=Stoch2)
{
ticket=OrderSend(Symbol(), OP_BUY, Lots, Ask, 3, Ask-Stoploss*Point, Ask+TakeProfit*Point, "-", 0, 0, Green);
ticket=OrderSend(Symbol(), OP_SELL, Lots, Bid, 3, Ask-Stoploss*Point, Bid-TakeProfit*Point,"-", 0, 0, Red);
}
the problem is it wil only buy..but i ned it to execute both order...thanks..

Problem migrating Indicator into EA as a filter function
When attempting to use part of an indicator as a function in my EA, I now realize that there are three types of functions. The first type is a Void which performs a process and returns 0. The second type performs calculations and returns one result. The third type expects to be given a set of specific values to process and then returns one result.
What can I do if my calculations produce three results which need to by used at least two different ways? Those calculations may need to be located in the Start() function for the following reason: Information flows from the External variables (which may be manually adjusted) and the Global variables (which remain static unless recompiled) into the various functions of the EA. The Start() function is the brain of the EA and reaches out to the other functions for their information. It may pass a set of variables to a function as arguments of that function if that function has declared those variables within it's () brackets. It then receives a result back and may pass more variables to another function to finish it's process.
Once I bagan to pass variables as arguments to other functions, I was hoping to enjoy a level of success with my EA coding. Unfortunately, I created a zero divide error, possibly because I tried to pass a value along as an argument from one function to another so that the value did not arrive were needed. Since it was actually missing, I got the zero divide error. My next revision removed intermediate steps and delivered values directly to the functions where they were used.
(I don't thing I do myself any favors by recording this point in my first two months experience learning MQL4 coding. However, anyone who may be googling "MQL4 zero divide error," might be glad to know how I managed to resolve it.)
My next EA revision cured my zero divide error, but the journal comment of my stratagy tester now indicated a stack overrun. For those googling "MQL4 stack overrun," I'll post the cause I found. It was failure to convert lots to their decimal equivelant by use of the "Points" constant when changing a price for opening or modifying an order.
The last tip I'd like to post here (after my initial two months coding experience and more than 12 EA rewrites) is a way I was able to solve a hard to find "unequal left parantheses" bracket. The MetaEditor does not highlight bracket text in color. If you have an AutoDesk product with Visual LISP Editor, you can open your MQ4 file in that editor and see almost all the bracket pairs in color. This makes it much easier to proof read for the missing bracket.
Thanks to everyone who shares their answers on this forum,
Happy Coding!
Any help?
Also wish to know if Metatrader orders can be run from the command line. Or in general if it is possible to interface external applications with Metatrader using some sort of API.
Thanks
