@myworld2u3 BTW i am using the online version. It has "compiling" problem where the directory of my computer does not appear like it used to, so i could not save the code as mq4 or ex4

I have been experiencing this problem right now. It happened quite a long time ago but it was rectified soon as people reported. I wonder if the current one is the same as the last time or my computer is the one having problem. TQ

It happened before. A glitch i believe and temporarily I hope.
