I have a code to generate random numbers from 0 to 1000, its is the following
int randomValue = (random() % 1000);
I want the app to generate it daily in a specific time for example at 10:00 am.
How can I do that??
I would like to answer : don't do that, you have an iDevice, not a 24/24 7/7 server. But perform this on a server side, and when required, ask your server for the values...

I'm just trying to use MATE to calculate response time between each SMPP submit_sm and submit_sm_resp, this is the mate script I'm using:
Pdu smpp_pdu Proto smpp Transport mate {
Extract cmd From smpp.command_id;
Extract seq From smpp.sequence_number;
};
Gop smpp_session On smpp_pdu Match (seq) {
Start (cmd=4);
Stop (cmd=2147483652);
};
Done;
So basically, it exacts command id and sequence numbers, then in Gop uses command id for start/stop
4 = 0x00000004 = SUBMIT_SM
2147483652 = 0x80000004 = SUBMIT_SM_RESP
This should do the trick. But, now what?
I added a column with Delta Time Displayed, and this should show the response time for each submit_sm_resp, but this is not using MATE, just calculate the time between each previous packet:
How can I use MATE script?
If I use the following filter in a specific column:
mate.smpp_pdu.RelativeTime
I only got the seconds, for each packet, from starting trace:
As far I understood, MATE should setup time between START and STOP, but which is the filter I should use?
This doesn't shown anything:
mate.smpp_session.Time
Please advise,
Thank you,
Lucas
Find solution! I posted here just in case someone need it:
Because cmd is a string, the correct Gop will be:
Start (cmd="0x00000004");
Stop (cmd="0x80000004");
This will did the trick.
I am trying to create a EA in mql4, but in OrderSend function, when i use some value instead of zero it show ordersend error 130. Please help to solve this problem
Code line is
int order = OrderSend("XAUUSD",OP_SELL,0.01,Bid,3,Bid+20*0.01,tp,"",0,0,Red);
error number 130 means Invalid stops.
so that means there is a problem with the stops you set with the ordersend function.
I suggest you set it like that:
int order = OrderSend("XAUUSD",OP_SELL,0.01,Bid,3,Bid+20*Point,tp,"",0,0,Red);
so you could use Point instead of hard coding it.
and to check what is the error number means. I think you could refer to: https://book.mql4.com/appendix/errors
You should know that there exists a minimum Stop Loss Size (mSLS) given in pips. "mSLS" changes with the currency and broker. So, you need to put in the OnInit() procedure of your EA a variable to get it:
int mSLS = MarketInfo(symbol,MODE_STOPLEVEL);
The distance (in pips) from your Order Open Price (OOP) and the Stop-Loss Price (SLP) can not be smaller than mSLS value.
I will try to explain a general algorithm I use for opening orders in my EAs, and then apply the constrain on Stop-Loss level (at step 3):
Step 1. I introduce a flag (f) for the type of operation I will open, being:
f = 1 for Buy, and
f = -1 for Sell
You know that there are mql4 constants OP_SELL=1 and OP_BUY=0 (https://docs.mql4.com/constants/tradingconstants/orderproperties).
Once I have defined f, I set my operation type variable to
int OP_TYPE = int(0.5((1+f)*OP_BUY+(1-f)*OP_SELL));
that takes value OP_TYPE=OP_BUY when f=1, while OP_TYPE=OP_SELL when f=-1.
NOTE: Regarding the color of the orders I put them in an array
color COL[2]= {clrBlue,clrRed};
then, having OP_TYPE, I set
color COLOR=COL[OP_TYPE];
Step 2. Similarly, I set the Order Open Price as
double OOP = int(0.5*((1+f)*Ask+(1-f)*Bid));
which takes value OOP=Ask when f=1, while OOP=Bid when f=-1.
Step 3. Then, given my desired Stop Loss in pips (an external POSITIVE parameter of my EA, I named sl) I make sure that sl > SLS. In other words, I check
if (sl <= mSLS) // I set my sl as the minimum allowed
{
sl = 1 + mSLS;
}
Step 4. Then I calculate the Stop-Loss Price of the order as
double SLP = OOP - f * sl * Point;
Step 5. Given my desired Take Profit in pips (an external POSITIVE parameter of my EA, I named tp) I calculate the Take-Profit Price (TPP) of the order as
double TPP = OOP + f * tp * Point;
OBSERVATION: I can not affirm, but, according to mql4 documentation, the minimum distance rule between the stop-loss limit prices and the open price also applies to the take profit limit price. In this case, a "tp" check-up needs to be done, similar to that of the sl check-up, above. that is, before calculating TPP it must be executed the control lines below
if (tp <= mSLS) // I set my tp as the minimum allowed
{
tp = 1 + mSLS;
}
Step 5. I call for order opening with a given lot size (ls) and slippage (slip) on the operating currency pair (from where I get the Ask and Bid values)
float ls = 0.01;
int slip = 3; //(pips)
int order = OrderSend(Symbol(),OP_TYPE,ls,OOP,slip,SLP,TPP,"",0,0,COLOR);
Note that with these few lines it is easy to build a function that opens orders of any type under your command, in any currency pair you are operating, without receiving error message 130, passing to the function only 3 parameters: f, sl and tp.
It is worth including in the test phase of your EA a warning when the sl is corrected for being less than the allowed, this will allow you to increase its value so that it does not violate the stop-loss minimum value rule, while you have more control about the risk of its operations. Remember that the "sl" parameter defines how much you will lose if the order fails because the asset price ended up varying too much in the opposite direction to what was expected.
I hope I could help!
Whilst the other two answers are not necessarily wrong (and I will not go over the ground they have already covered), for completeness of answers, they fail to mention that for some brokers (specifically ECN brokers) you must open your order first, without setting a stop loss or take profit. Once the order is opened, use OrderModify() to set you stop loss and/or take profit.
How can I set Jenkins to run a job at a particular time?
Like if I'd like to set it to 8:30am every weekday and this is what I could do
H 7 * * 1-5
this randomly picks up 7:35am as running time.
H is a pseudo-random number, based on the hash of the jobname.
When you configured:
H 7
you are telling it:
At 7 o'clock, at random minute, but that same minute very time
Here is the help directly from Jenkins (just click the ? icon)
To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible. For example, using 0 0 * * * for a dozen daily jobs will cause a large spike at midnight. In contrast, using H H * * * would still execute each job once a day, but not all at the same time, better using limited resources.
The H symbol can be used with a range. For example, H H(0-7) * * * means some time between 12:00 AM (midnight) to 7:59 AM. You can also use step intervals with H, with or without ranges.
The H symbol can be thought of as a random value over a range, but it actually is a hash of the job name, not a random function, so that the value remains stable for any given project
If you want it at 8:30 every weekday, then you must specify just that:
30 8 * * 1-5
Take a look at http://www.cronmaker.com/
0 30 8 ? * MON,TUE,WED,THU,FRI *
30 8 * * 1-5
This would start at 8:30am Mon-Fri.
0 and 7 are Sundays.
Not sure what the H does but I am assuming it takes the lower case hex of h and applies 68 which is 35 in decimal... lol. Don't do that.
Following this format:
Minute Hour DayOfMonth DayOfWeek Day
It picks that time because you told it that it can, as imagine you already know:
minute, hour, day of month, month, day of week.
Now you have user H which allows Jenkins to pick at random. So you have told it to run between 7-8 every week day.
Change this to:
30 8 * * 1-5
Hope this helps!
I want to print the system time in hh:mm format, and store it in AM array or PM array, depending on what time it is.
Here is what i have:
assume cs:code, ds:data
data segment
hour db ?
min db ?
AM db ?
PM db ?
data ends
code segment
start:
mov ah, 2Ch ;
int 21h
mov hour, CH
mov min, CL
I know that function 2Ch returns CH = hour. CL = minute. DH = second. DL = 1/100 seconds
How can i use this, to print the current time ?
Any ideas?
(I am using TASM, TLINK, and turbo debugger)
You'll need to look up some kind of system call for writing to a console (I think there are actually some BIOS routines that do this if you're not running under a mainstream OS) or link your code with a library that provides a printing function and invoke that.
That's how you printing string: An Introduction to Assembly Instructions
That's how you printing decimal number: Print decimal in 8086 emulator
I have this line, which shows the minutes and seconds. But I have to add milliseconds to it as well for greater accuracy. How do I add that in this line, or is there an easier way to get the desired result?
#duration = [cd.ExactDuration/60000000, cd.ExactDuration/1000000 % 60].map{|t| t.to_s.rjust(2, '0') }.join(':'))
The exact duration type is saved in microseconds. So the first converts to microseconds to minutes, the second part is microseconds to seconds. Now I need to add milliseconds.
cd.ExactDuration/1000 % 1000 should do the trick.
Of course you may also want to tweak the formatting, since that's a datum you don't want to right-justify in a 2-wide field;-). I'd suggest sprintf for string-formatting, though I realize its use is not really intuitive unless you come from a C background.
