# WHEN WILL THE IRAN WAR END?? I NEED TO FILL UP MY GAS

Dude you need to calm TF down, lol. No, you don't need to learn additional concepts. You actually already know how to trade because you do it all the time.
You go get gas, you traded USD for GAS. Nothing stops you from keeping that gas in your car and selling it next month to your neighbor for a profit (thus doing GAS to USD). And you sure AF don't need a whiteboard full of concepts in order to figure this out, you just know a good price would be like $2 and a bad price would be like $4, so you buy at $2 and sell at $4.
If you're confused because you're trading one currency for another currency, then just trade something else. Go trade like corn futures, you buy when it's cheap and sell after the "super El Niño" this year or whatever takes out everyones farm.
Looking at your post history. Let me ask you this: are Casio AE-1200 watches cheap right now? Because I know you can answer that without all these concepts. If the answer is "yeah they're cheap right now" then what prevents you from trading it? If you think future price will be higher, just buy low and sell high. If you think future price will be lower, borrow a watch from someone, sell it right now, and then in a month or whenever prices drop you buy the replacement. Pocket the difference.

You said GAS fee. Don’t move the goal posts.

Dude... Think about it logically for just half of a moment, please.
If this was actually gold, why on God's green earth would you be buying it from a GAS STATION?!?!?!

I'm considering it. I'm a hobbyist photographer, pretty much just bring my camera on vacations. I currently have a fuji xt20 with a 23mm and 50mm prime. I love just shooting jpegs and not having to mess around with editing raws.
I've been having a case of GAS and wanting to "upgrade" for better autofocus. I have a kid on the way and see myself shooting a lot more.
Is it actually worth the jump to something like sony A7 whatever or nikon z6 or similar model?
