Comment(iOpen) shows value of "0.0" - Is my script too fast? Or my PC / internet connection too slow?
kiikek: I need to know why this is happening.
On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors
before accessing prices.

Hi everyone,
I'm new to coding and have encountered a problem.
I wrote this script and compiled it with no problems.
I then open a new random chart, say AUDJPY. And then I drop the script on to the chart.
But the number being displayed is simply "0.0". See for yourself, I posted a screenshot:
A few seconds later, I close this chart. Open a new one and drop the very same script onto the chart again.
![the same script..on a new chart..after waiting a few seconds the same script..on a new chart..after waiting a few seconds](https://c.mql5.com/3/266/12.PNG)
This time, it shows me a value, and a correct one at that. See screenshot:
Is there an explanation for this?
Could it be my computer being very slow? And it had to wait for a few seconds first before it was able to "pull" this piece of information from the broker? And then, when it already had this piece of info and I tried to retrieve it again, it was able to simply pull it from the history center table (F2)?
Because my computer, a notebook from 2007, is indeed super slow (I needed 387ms just to compile this simple script).
Please help, I need to know why this is happening.
