Boll Squeeze with JMA for MT4
u basicly have the Bollinger band squeze indicator, here is a more faster version(not by much)..make sure u have the jma.mq4 indicator
let us know if it's for any use to you.

Hi Spahiu,
Thank you for posting the code above. Greatly appreciated. As you say, it is a little faster, a couple of bars sometimes on the same settings so that's a great improvement on its own. I will experiment with the settings later to see how the JMA low lag can cope.
By the way, it is also a very good indicator to keep you out of flat markets. Set the colours to blue, white, white, blue. When the 0 line dots are white, keep out.
Cheers
Chris
dongaging,
here is another indicator to drag into the same window as your squeeze, so you can see where it is happening

Hi maumax what is squeeze indi can you post one here
Here is the Squeeze indicator by Nick Bilak, I found the indicator works better for me with the following settings
extern int bolPrd=20;
extern double bolDev=2.0;
extern int keltPrd=18;
extern double keltFactor=1.7;//1.5
extern int momPrd=14;
Put the bbsqueeze on your chart, then add the indicator from the previous post in the same window.
This squeeze indicator has already been posted in text form, in this thread

Thanks man 
How to use ?
How to use is found in the photos, also attached is the dayimpluse indicator, I find it great for making sure you enter the correct direction for the day, just drag a 34 ema into the window with the indicator
how do I place the 34 EMA over the DayImPlus indicator? I drag the EMA over but it doesn't work. I'm using MetaTrader4. Please upload your template. Thanks.
banzai, check out https://www.mql5.com/en/forum/194277
Note that EMA (actually "Moving Average") must be built-in indicator, not custom indicator.

The code below provides a nice indicator for MT4. Can someone advise on what code to insert to get it to calculate on JMA based boll bands if possible. If it works it should be a great indicator
