Zed Laning Phase and Trading

Hello everyone.

By reading the title you know what this is about,I'm a main for a very long time now,yet i still don't know a way of managing to get good/decent CS without getting poked,especially against ranged champions such as ,, etc. or even some champions who are just extremely aggressive such as . The difficult thing is that if i try to farm the ranged champions always poke me with autos which eventually leads to a Recall and to a loss of CS and XP and if i try to trade with them i miss my CS it's kind of a tough situation,can someone please tell me how to deal with that without getting poked?I'd appreciate it a lot.

1. Now moving on to aggressive champions.The thing with them is that i always miss CS or i get out traded. For example laning against can sometimes really be hell for me,leaving the fact that VS. is a skill match up it really is annoying cause when he dashes at me either i am forced to stay under tower or if i fight him he just out trades me cause of minions (Enemy and Ally) and there is not really any hope of winning a trade with him levels 1-5 at level 6 i do have a chance but problem is by then i'd either have 1 or 2 deaths or be 20 or more CS behind him and he'd be a level ahead.If someone could give me tips on how to have a stable laning phase that would be Great.If you've read this far,thanks for reading .
