i simply can not understand this game
i try to use the trade office but what do i use the trade house but what do i do with it! and i try and go to different towns to trade but i just keep on losing money even if sell iron i just don't know what im doing!

can any one help?

but why would i want to have 2 ships or do auto trade when i can just do fine with one ship? what is the point of auto trade?

You'll need to have more ships when the amount of goods traded just can't fit on one ship, and also, because eventually you should trade with multiple towns simultaneously.
The point of auto trade is not having to pay attention to all your towns and fleets. Personally, I only use the auto trade option of the trading house, no automatic trade routes, but that's my own preference.

i see now but when should i get another ship and start auto trading. since i am still only using the starting ship with nothing else

I would say, first just experience the game - learn about the products, what sells good and where, what's worth trading and what shouldn't you bother with, and most importantly, learn the prices of the various goods.
When you have a good estimate of what's a reasonable price to buy something for, you can hire an administrator and set up auto trading.
About more than one ship, you should have a second one built whenever you feel your beginning snaikka is not enough anymore.

Another way to look at the trading, is to buy plentiful items and sell scarce ones. If a port has 50+ of something, you can probably buy some of that and make a profit later. But you want variety, so stop after you have some of a good. Where ports have single digits of an item, it's a good thing to sell to them. You can figure out more exact notions of how trades work as you go, but remember you're buying plentiful and selling scarce.

Hey, I'm new to the game (just picked it up on sale over the weekend), and I found this thread helpful so I thought I'd pitch in a couple of thoughts.

First, all the advice others have given so far is good advice.

The intro to the game makes it seem like you're specifically trying to trade for your home city. This prompted me to try and make long voyages just to get goods to bring back to Lubeck for sale, but that's a mistake. At first it's much better to make short hops from port to port buying and selling whatever has a good price at the moment. You'll also learn about which goods are produced in the different cities. Eventually you'll be able to spot good prices just by glancing at the list.

Second, you want to buy small amounts of many different products, rather than large amounts of a few products.

There are exceptions as the game develops, but this is a good plan when you're just starting out with one ship.
