This is the part 1 of my Warframe trading guide. It is followed by the transcript.
What is trade in Warframe?
Trade in Warframe means 2 Tenno can exchange at least one but at max 5 tradable items with one another. The number of items that each tenno brings into the trade does not need to equal. They can trade one mod for 5 prime parts or weapon part for 7 platinum and a mod.
Where can you trade?
Either at a trading post in the clan dojo or at Maroo’s Bazar (caveat: additional hub tax). To trade at a trading post at least one Tenno has to be in a clan that has built a trading post.
What can you trade?
all mods of all ranks but not Legendary mods from your daily login (Primed Fury, Primed Vigor, Primed Shred)
all prime warframe bp and prime warframe part bp (no build parts)
unranked weapons, weapon parts, mods from syndicates
Alad V nav coordinates
special weapon parts from invasions (e.g. Karak Wraith, Snipetron Vandal) or from events (e.g. Imperator Vandal)
Unranked weapons Baro ki’teer sells
Ayatan statues and stars
relics of all refinements
arcanes, arcane helmets
imprints for kubrows & kavats
scenes for captura
What can you not trade?
resources (e.g. kuva, nitain, endo)
regular (non-prime) Warframe parts
forma, orokin reactor or catalyst, including blueprints
platinum for platinum
When are you allowed to trade?
When you reach MR2
How often can you trade?
The number of trades equal you mastery rank. E.g., a MR6 player can do 6 trades and MR24 player can do 24 trades per day.
For every item you receive you have to pay a trade tax in credits. Trade tax normally varies between 2’000 and 10’000 credits. If you trade for a legendary mod – meaning receive a primed mod – you have to pay 1’000’000 credits per mod. Receiving platinum results in 500 credit trade tax per 1 platinum; e.g. receiving 30 platinum costs 15’000 credits, receiving 250 platinum costs 125’000 credits.
Clan and hub tax
Clans can impose an additional clan tax for each trade but this is very uncommon nowadays. Maroo’s Bazar has a fixed hub tax of 10% on top of the trade tax.
