Snowballs and the anti-grid

I haven't tried your EA yet but it appears that IBFX (an NFA broker) does some back-office tricks to allow you to get around the FIFO rule and close your positions in any order.

Here's their release regarding their FIFO handling:
http://www.ibfx.com/Corporate/post/2...FIFO-Rule.aspx

Now, only if they would allow hedging!

Hedging is not needed.

Got that right.

To me hedging is not only not necessary to the method in this thread, it's not necessary in general. It creates a psychological illusion of safety without really doing anything useful.

Disagree, and wasn't talking about only this strategy. Everyone trades differently, the forums are chocked full of 'experts' on how to trade and that one person is right or better than another. To each their own...

IMO it all depends on how you choose to trade and no method is better than the other really, it is a just a matter of how good you get at doing it and handling your emotions whether you do hedging or not....

Please from here on no more postings in this thread that mention the word "hedging".

I've just been reviewing and testing this code - truly AWESOME

I'm a professional programmer and you have some well thought out and well written code here. Probably the best I have seen on FF.

Many thanks for sharing

Hi everyone

Well i put the file in correct folder. It show on my navigator window but It does not work.

Could anyone tell me why it is not working on MT4?

Thank You in advance

Have you given thought to have the snowball start from a limit order

Whatever you like, your thread. As a swing trader, sometimes trades in the opposite direction are good whether you call it 'h*!%)#g' or not. Sorry to have offended you guys.

If we put a line to trigger trades each time it hits line will it open a new trade ie let say it bounces up and down around the same point for 10min will it trigger 10 orders?

i am using this indicator and trying to locate where to put start short start long.

can you help please, as you can see i have added the start short and start long and they appear on my chart but i am not sure they are triggerig any thin correctly . I have your ea on sveral pairs to demo and see how it might work

Ok solved issue of description now being added to object list (see attached - yet it still is not triggering trades any ideas why this may be the case?

[edit, deleted] sorry, I was too fast, forget my initial answer.

Let me think about the problem for a while.

Lets solve this step by step: When the lines immediately change color and style so that they become magenta and dashed instead of solid this means they are recognized by snowball as active trigger lines. does this happen?

I think i have an idea what the problem is:

I have marked it in red. first it should not delete the line before creating it, secondly it should not set the third coordinate, leave away the two zeros at the end.

Snowball will internally use PRICE3 of a trigger line to store the last bid value so it can detect a line crossing. deleting and recreating this line on every tick means snowball will perceive this line as completely new everytime and will not be able to remember the last bid value that it has compared against this particular line.

Modify the indicator so that lines are not permanently deleted and re-created.

I know that you have alot on but i am trying to use some combinded indicators with your ea.

What i wanted to do is as follows:-

i have an indicator on the chart which provides a variable icolor[shift] which produces as you can see -1 or 1

_-----------------------------------------------------------
if (haOpen[limit+3]==0.0) haOpen[limit+3]=Open[limit+3];
haClose[limit+3] = (Open[limit+3]+High[limit+3]+Low[limit+3]+Close[limit+3])/4.0;
for(shift = limit+2; shift >= 0; shift--) {
haOpen[shift] = (haOpen[shift+1]+haClose[shift+1])/2.0;
haClose[shift] = (Open[shift]+High[shift]+Low[shift]+Close[shift])/4.0;
int ic;
if (haClose[shift] > haOpen[shift])icolor[shift] = 1;

else icolor[shift] = -1;
return(icolor[shift]);
// blue 1 red -1
-------------------------------------------------------------------

now i am trying to get this value into a second indicator which draws lines to trigger trades using your splendid ea

i want to use the vaiable obove as confirmation and to change the description in indicator two. to do this i need to get the value into the 2nd indicator

i tried the icustom indicator

ie double ic=iCustom( NULL, 0, "indicator1",icolor[shift],0,0);

but to no avail

if i can get the value in to indicator 2 i can do the rest as i have done this manually and it works triggers trades as condition is confirming

thank you and thank you with the previous help

you also have the option to modify the EA itself: Insert a function (call it autopilot() for example) and call this function at the beginning of onTick() or onOpen(). Inside this function you call all your indicators, put all your logic and if it want to instantly start trading then call go(LONG) or go(SHORT) or if you want to stop then call stop() or pause(). Calling these functions is equivalent to actuating one of the buttons.

But if you want to work only with lines it might really be better to do the line drawing in a separate indicator and not create (and maintain) a modified version of the EA.

It seems to me that you are relatively new to coding and the usage of mql4, the way you are trying to use for example the iCustom() function tells me that you are not only not familiar with mql4 but with the basics of programming and programming languages in general.

The problem you are trying to solve is not extremely difficult but it is clearly above your current programming skill level. I suggest first learning the proper usage of mql4 and the concept of indicators in general with much simpler examples until you are familiar with all elements of the programming language, fully understand what is going on behind the scenes, what you can do and what not and then finally how to solve this specific problem.

Every one of us has started his programming life at the point where you are now and it took all of us a long time to learn this skill. This is completely normal, there is no shortcut.

Usually I try to teach the people how to fish instead of giving them fish on demand and this is the reason I won't sit down now and try to solve your specific problem. Trying to teach you programming would be possible but not in only a handful of postings and not in only a few days and a full blown programming course would clearly go beyond the scope of this thread but you might be able to find patient and skilled teachers on this forum.

If you don't want to do (learn) it yourself then maybe somebody else (not me) would be willing to code it for you, maybe it would be even worth a completely separate thread.

sometimes the price will reach a pending order initiating a trade at 1.2100, move away and then return to 1.2100 initiating a second trade at the same price. how can i stop the ea from re-creating a pending order at an old entry point without resetting, pausing or turning off the ea:


_______________________1.2100
---entry1
-----------------entry2

This should not happen. is it at the exact same price or 1 or 2 pips away?

Are you moving/trailing the stoplosses? the stoplosses are used to identify where an order already exits. Some NFA-regulated FIFO brokers are messing with the stoplosses and silently trail all older stoplosses to the newest one without notice. If the stoplosses are not left where they are initially placed the EA will not function properly and produce duplicate orders.

under rare circumstances it happens that when the first entry is trailed it will not trail all of the stop orders correctly. I am still investigating what causes this bug. In this case the duplicate orders are a few pips away from each other and not at the same price.

If you see for some reason such a duplicate order you can move the green line with the mouse just one pip away, moving the line with the mouse will adjust the exact grid position and reset and re-create all pending orders. Then move the line to the pip exact back to the current grid level.

Opening the properties dialog and then closing it again with [OK] will also reset the pending orders.
