Beginner's Question: Does Start() run after each tick ?
Is Start() called after each tick?

I am using the strategy tester to cycle through a few days worth of data with a 1M scale and I have the following line in my Start() routine:

Print(Ask);

I expected to see a Journal entry for each and every tick. When I start the strategy tester with a slow playback setting, I see the chart updating but I do not see the Ask price being printed to the Journal very often. The Ask price is only sent to the Journal about once every 15-30 minutes.

Why is this?

Is it possible to create another tab in MT4 or a debug window in the editor to which text can be sent?

Thanks,

Forexwindo

Exclamation More than One Order
Hi,

i´ve got a question: how to allow the expert to place more than one order independently?

Using the command (or another command if anybody know)

total=OrdersTotal();
if(total<1)

we got the control of the number of trades being executed simultaneously (if < 1, one at a tima, if >2, two at a time and so on)

But in real world, that command ends up with the expert placing two or more orders using the same entering conditions (same as using several lots).

I want to allow the expert to place another orders even if there is one or more orders opened, but not place them at thge same moment;

HOW TO ALLOW THE EXPERT TO PLACE MORE THAN ONE ORDER, WITHOUT PLACING THEM AT ONE TIMA?

thank you, waiting for help!

Red face EA for only once per tick
Hey guys,

I don't know if this has been posted before (I lack the patience to search through threads, sorry!) but I know it's been asked for a lot.

This code will ONLY run once per tick. It will run as soon as a new tick is introduced, and only then, and not function afterwards until another occurs.

Please keep in mind that can actually be a problem, at times. If your orders don't go through, for whatever reason, it will not initiate again. If you want to modify the code to do so, go ahead. I would suggest something like:

Code:
if order fails, fileseek to front of f, write Open[2] to f
This will make the next tick believe it's a new one.

Are there any books, online tutorials or videos on writing MQL4?

Hello All,

I need help coding this:

Based on a daily chart:

a) Let's say my conditions are met on closing on day#1 and let's assume day# is June 9.
b) Now i want to place a BUY-Stop and a sell-stop at the High and Low on closing on day #2 or june 10
c) Finally, i want the trade to be triggered on day#3.

Additionally, if the LONG is triggered first, i want the sell-stop to be closed and vice-versa.

Thanks in advance for your help.

regards,

forexcel

EA for appointing day of a week ,and time
Do not you know EA which you choose the day,(For example, only Wednesday and Thursday)　and appoint time for opening and closing?

In many cases,
A rate rises on Wednesday and　Thursday since many people to get the SWAP.
I buy it at this time and take a position.
And the rate falls as soon as an SWAP occurred.
I am sold at this time and take a position.

I am looking for EA to use for like this trade.

//+------------------------------------------------------------------+ 



......but I don't understand how to put the code below inner it.

PHP Code:
...

 for (int i=0; i<OrdersTotal(); i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
      if (OrderSymbol()==Symbol()  ) 

return(0);


.... 
The last block of code that I've written is: "If one order on one SYMBOL has been already opened, do not open new orders on that SYMBOL".
Can someone help me to integrate it?
Thanks,

Mauro

EA only makes one trade...
Hey guys, I have a quick question for you. I recently created an EA. The parameters are correct and when I added it to the chart, it placed an appropriate Buy and then later a Sell. But, the next time a Buy signal came, it never placed a trade. Seems that the EA is only taking the first trade and then none thereafter. Any idea why this might be? I'd appreciate any help. Thanks!!!
