Can someone please explain why this indicator does not update itself automatically. It will give you the sell and buy dots when you first attach it to the chart but then it will not follow the chart movement and will not give any more dots.
An idea please. The indicator is SHI_SilverTrendSig.mq4 and I insert it below.
Many thanks. Please see below:

/* It is the optimization option. We have the function here which restore/return the number of counted bars in very special way.
During the first indicator's call we have 0: it is normal because it was not counted anything,
and then we receive the number of bars minus 1. For example, if the number of bars equal 100,
we will have 99. I did it especially, you may see that NB is the number of bars whioch should be counted.
You know we may throw out this parameter. But for the people who understand we may keep it. So, during the first call
of indicator this NB is the same one but during the 2dn etc calls - reducing the value up to the last bar,
That is 1 or 2 for example*/
