Hi everyone, for people using the sexy stochastic strategy developped by Boxingislife this will be a big helper

You can find the strategy here :

I have finally decided to release this indicator to the wild as i believe that it is not the indicator that matters, it is the trader.

Attached is the indicator with the code. I have documented it pretty clearly but i intend to make a guide for it.

The alert system has been corrected by ACS. Big thanks to him

I has one issue i hope the community will solve. The alert and mail system is working but it sends 4 time the alert (one for each subsequent candle, see this topic http://www.forexfactory.com/showthread.php?t=58380 for more details)
Hi melpheos,

I will take a crack at it. It looks like some people have suggested somethings and you are going to check them out (from the other thread). I have two questions (assuming the following chart signals show the case-numbers of this indicator):
1. whether the repeat mails are always four or it varies (from the chart in main thread, it can be 1-5 signals for each case, case2 having most repetitions)?
2. Are they really on consecutive candles (from the chart you posted in the main thread, I expect them not be consecutive)? If it was 4 consecutive signals for each instance, the case2-buy in the following post chart would produce 16 emails!!!

If these are silly and not correct, pardon me. I thought these may have some relevance to the problem.


On a different note, you have put the email alert inside the pop-up Alert and if DisplayAlert is disabled, email also will be disabled. I think they should be seperated.

chandra

1/ Allways four times whatever the case as far as i can tell. Of course, if a new signal appear before the 4th candle, the alert will be replaced by the new signal (for example an up trend case 1 followed by an up trend case 2)

2/ As explained by someone on the first thread i made, the indicator gives an alert for each candle where the situation is verified. As the indicator check the status of 3 candle back in time and put the signal on the first candle, we can assume the loop occurs 4 times and give 4 alerts.
I can take a screen shot tomorrow of the alert occuring.

As for the email alert, this line
Inserted Code
if (emailAlert) SendMail(message + Symbol(), message + Symbol() + " , " + Period() + " minutes chart");
should check if the email is enable or not.

Hi melpheos,

I don't see any loop occuring 4 times. MT4 checks upto two past candles + current one. But I don't think that is the problem. Because my alerts don't do this repetition.

I think the main problem is that you are defining the CaseShown booleans inside the start function and reinitializing at every tick! So, the information about last tick is lost everytime. Only lastAlertTime in the SendAlert function stops it from sending the alerts every tick! The booleans must be defined before init function and should not be initialized inside the start function (you should treat these booleans just like you are treating the lastAlertTime). In that case we don't even need the lastAlertTime control. Please check this. I think this must be the reason and four candles may be just a coincidence (may be it takes four bars to get past that condition).

About email, I am mentioning that the email routine will be called only if the DisplayAlert is set to true (then pop-up also will come and we cannot have email without pop-up, though we can have pop-up without email).

chandra

I personnaly did not want the email alert only when i created it and, as i had this repaeting alert problem i forgot about it, but you are right on the logic of the coding. I'll change that as i may want now to receive rapid alert (popup) on some chart and not others and email alert for longer TF chart.

As for the 4*time i dont really get your explaination I'm not a very good coder)

Hi melpheos,

Here are the three problems.

1. Anything that is defined inside a routine will be re-initialized when the calculation are performed at next tick. That values are never kept safe. The Case1_Shown type of things when you define inside the start function, will always have the start value as zero (means false for boolean). So, initializing it is uncessary. Then, whatever value they were assigned in the last cycle of calculation will be lost. So, if the Case1_Shown was set to True in the last tick calculation, it will be reset to False automatically at the end of that set of calculations (so for every new tick the Case1_Shown will start as False). So, if you want the last data to be remembered, it must be defined where you have defined the lastAlertTime (outside of any function, I think these are called global variables).
Solution: I moved them near lastAlertTime (made them global variables).

2. Also if you keep re-initializing, the whole point of saving is lost. It will work only until the end of the rest of the loop and again at every new tick that value will be False and you will get new alert (only the lastAlertTime control saved you from getting the alerts at every tick).
Solution: I added initializing at very different places.

3. You are not checking if Case1_Shown was true while checking for conditions of Case1 (others also). I think (I am not sure on this), we don't want to check for Case1, when the Case1_Shown is already true. So, in that list of conditions for each case, you have to add extra control to check if the Case1_Shown ==False, before checking fresh. Here we may get confusion because both up and down conditions use the same variable Case1_Shown... May be they have to made as two different sets.
Solution: I made the extra conditions, and made them separate and added a set of Case3_Shown also.

I don't understand how the calculations work and whether it is possible for the conditions to be true at consecutive candles. So, I am not sure whether the changes I made will fix the problem or add more! I attached to a chart and checked for the signals and they seem to be OK. I did not check the alerts. Please check if this works as you expected. I don't understand the fourth set of calculations (which has two types), but since it did not have alerts, I did not bother much.

Also I fixed the Alert and Email functions. Now they should function independantly.

Please check and let me know if they are any better!

Regards,
chandra

EDIT: I think it may have a problem of Alert and Email for past signals also (that will be too many). If you get such signals for past Cases, it needs to be fixed in the call to sendAlert by changing as shown below (in all 6 places; i < 3 is OK or i == 0 should be used, I am not sure):
Current line:
Quote
SendAlert ( " Stochastic Downtrend Case 3 : "); }
New Line:
Quote
if (i < 3) SendAlert ( " Stochastic Downtrend Case 3 : "); }

No change

It still repeating four times like previously...

The timestamp of the alert are a bit weird that is because of the late hour and the market is not very active...

Hi melpheos,

I am sorry that my last work did not fix the problem. I also checked just now on 1M chart and it did the same. I had to do a crackdown on the code.

I threw out all the Case_Shown things from the code. Because the symbols were appearing correctly, I used those for making the alerts also (my programs use this way). In order to make this work, I had to make the buffer initialization values to zero (the earlier used EMPTY_VALUE gave the repeat signals even with this modification).

Now for the two signals I got, there was only one alert for each (it was 1 and 3 -up cases, 4 down case did not show signal, because I did not program it, but it can be added easily).

Please check this out and let me know. I am hoping to see a smily face!!!

chandra

i'm testing it now but its late and even on M1 i will probably not have an alert now.

I'll check tomorrow but the fix seems to be a pretty good idea, did not though about this

Only one problem, dropping the case_shown now can give multiple alert when there is mutiple signal on the same candle (down and up signal cannot appear at the same time but signal 1 and 2 or other combination can appear at the same time ^^ ) I think i can survive with this as this does no occur all the time

Thanks again for the work you are doing.

edit : i just had an alert on M1 and it seems OK but i also changed the settings so the signal does no repaint above each other and there is quite a lot of mutiple signal doh

Whooooowhoooo big thanks... It's working as e xpected now. You can't imagine how happy i am. Well maybe you can

I now have to work on the alert logic so it does not show too many false alert and it will be near to perfect ^^

I'll had a MSN alerting as well, might be handfull because i have just registered an unlimited MSN/Mail/Web access on my mobile (but i can't send phone call ^^ )

Finally I am happy to see a smily face. I understand how it will feel to resolve the difficult problem and shout Eureka! I hope to see your improved version. I don't know much about this method and I have to check it out.

You can make the email to become SMS (I think only paid services do this), but no phone calls yet!!!

Is this what the chart should look like (attachment)? Bear in mind that I have my own one at the bottom and another one a 'non lagging indicator' in the main chart.

Sorry for the late response, well i can look like this or differently.

I'm not using sexystoch anymore (only from time to time) as it's not really reliable on daily chart and that allmost all the time i have most of the time.

In fact, my charts looks much more simpler than that now. I have only one stochastic, a moving average and a fractal (and the fractal is not very necessary but its easier on the eye)
