No, this thread is not about how to do the apato fossil method in the TH. You can find enough information about this in the forums. If you don´t know the basic method you should watch this tutorial by @Sionsith.
I want to talk about even improving that a little to get more of a specific resource. Let us assume everybody wants to maximize the amounts of bucks.
As you all might know there is a maximum of trades which can be in the TH. As far as I know it is 6 or 7. If this maximum is reached, no new trade will appear until the oldest one expires or you accept a trade. You also have to know, that there can just be 1 apato trade per category, so it is impossible to get apato to coin twice in the TH for example. And this how you can use this functions:
This are all the trades which are in the harbour after the night for example, so that the maximum is reached and a new trade is already waiting to come in. (I have a clean market in exception of apato fossils.)
Apato to coins
Apato to food
Apato to bucks
LP to creature
Bucks to decorations
Food to coins
(Another trade will come in if one of the trades expires or get accepted)
Here you see 3 Apato trades. Now you need to accept the trade Apato to Bucks FIRST. Then you have a higher chance, that the trade, which will come in instantly, becomes another Apato to Bucks trade, because the Apato to Coins and Apato to Food trades are already blocked.
If you have any questions to this feel free to ask here.
