Generally I don't start trading for the first 100 years because the CoTs that I'm generally in (Genoa, Mecklemburg, Flanders, Novgorod), are really weak.
Once I'm close to level 3 I generally start trading and once I reach Level 3 I try for a monopoly in my home CoT.
I know everyone hates the auto-send option but once you are firmly in control of your home CoT, I just leave it on so that I can kick everyone out and dominate 100% of the trade.
You just have to watch the computer because sometimes they get very stupid. I was losing a lot of money in my Italian game and I couldn't figure out way. Then I saw that the AI was sending merchants to Malacca at 30 ducats a piece. Stupid computer...
This is poor advice on all levels, I'm sorry.
First: about Auto-Send.
DON'T DO IT!!!!!! The computer, as
Alessandro notes, is stupid. It does very wasteful things, using up huge chunks of money better spent on nice things like manufactories and ships and stuff. It pisses off other countries, who hate it when they have their own merchants competed out of their own CoT's, the result of which is you end up with Trade Embargoes that you didn't intend on, severely impacting your income.
Second: You NEVER want to have 100% of the trade in a European CoT. This will result in the eventual loss of the Center. There is a specific algorithm for this; in essence you want most if not all the slots filled with traders. Monopolize if you like (it gives you added merchants), but don't do so for the purpose of receiving the added trade from the unfilled slots. Save that for New World CoT's. And trust me, it happens. I've seen it more than once.
As for the Original Post:
1. Start sending traders right off the bat. Use the empty-slot method, because it is simply the cheapest alternative. Many here prefer to avoid the really highly competitive Centers, like Veneto and Liguria, because you are more likely to be kicked out with all the merchants knocking on the door trying to get in. It makes much more sense to have three merchants quietly earning a portion of the trade from a 100d Center than have one merchant in and out of a 300d Center. Look for Centers where fewer countries have merchants present.
2. Early on, don't look to keep too many traders in a Center, unless it is a Center that you own. Austria doesn't have a Center to start (one appears later by event), so you are forced to send to Veneto as the cheapest location, where you have no competitive advantage. Instead, look to find empty slots all over the continent, because the fewer the places you hold, the less likely that an attempt to gain entry to a specific Center will result in you losing a merchant. Austria doesn't have an advantage in Trade tech (like Venice and Genoa do), so you are playing for the long-haul here.
3. Keep an eye on your budget. Remember that even at 6d or 7d a shot, if you send all the merchants you are entitled to out in a year, you are talking a substantial portion of your yearly income at the start of the game. Don't feel compelled to do that. But you are missing a bet if you don't gain trade income early; you put yourself substantially behind other nations in the technology war. Remember: you are converting Treasury to investment with merchants, so it isn't just a matter of calculating a "payback" of cost.
knul, the number of merchants DOES have an effect, but it isn't out of proportion to the simple fact that you have more merchants. That is to say, if you have 4 out of 20 slots, your chance is increased over having 1 out of 20 slots, but its a proportional increase.
