https://i.ytimg.com/vi/I_t4EYBsTD8/maxresdefault.jpg As mentioned in my previous article about Warframe's in-game economy, you can trade in-game items for platinum instead of buying it using real money. Here is a detailed guide on how to do it. Things You Can Trade
Not every item in the game is tradable. Here are the types of items which you can trade: a) Prime Warframe Parts and Weapons
Regular warframe parts and weapons are not tradable. Note that you must trade the blueprints. Once you craft a blueprint or any part of a frame you can no longer trade it. You obtain prime items from opening relics: https://i.ytimg.com/vi/zsMEsLM4MxM/hqdefault.jpg a.1) How to Obtain Relics Relics are obtained as rewards from completing missions. The most recommended types to obtain them are interception, defense, and excavation missions. Relics are divided into 4 tiers namely lith, meso, neo and axi. To know specifically where a specific relic drops, go to you codex ---> universe ---> relics and click the relic you are searching for. If you want to know which relic drops a specific item, go to you codex ---> universe ---> relics and type the item name in the search bar. It will filter out the relic/s containing that part. a.2) Refining relics Each relic contains different items that are classified per rarity. You can view the items by click on a relic in your relic segment. The brown ones are considered common drops, silver is uncommon and gold is rare. As expected, the rare items sell for much much more. If you want to increase the chances of getting the rare drop, you have to refine the relics. In order to refine them, you have to do void fissure missions. You can view these missions in the top right corner of your navigation under this symbol: https://vignette.wikia.nocookie.net/warframe/images/5/57/VoidTearIcon_b.png/revision/latest?cb=20160713085454 a.3) Opening relics You also open your relics during void fissure missions. ALWAYS do void fissure missions in squads, this way can choose which among your squadmates rewards you take as your own. This means that if one of your squadmates obtain a rare drop, you can choose that as yours as well. *PS: You can also sell the relics themselves* b) Mods
Mods are item customization cards that strengthen warframes or weapons. You can view the mods you have from your mod segment. https://dsd6pi3jct4ey.cloudfront.net/wp-content/uploads/2017/11/2-25.jpg Like relic drops, they are also classified by rarity. Brown ones are common, blue ones are uncommon, and the gold ones are rare. b.1) How to Obtain Mods Mods are dropped randomly from every mission. However, some special mods are only obtainable from specific mission types or events. These mods are a rarer and therefore sell at much higher prices. If you want to know where a specific mod is obtained from, go to your codex ---> universe ---> mods and click on the specific mod you are searching for or simply type its name in the search bar. c) Ayatan Stars and Treasures
Ayatan stars are random drops during missions. There are two types, cyan and amber. Amber stars are rarer and therefore sell higher. https://steemitimages.com/DQmXc91ocejX3iLDPa2JQbbDYdodvSam24FyDXo47nwswyd/image.png https://steemitimages.com/DQmXsWrhoxvr2bd5xGV1Mw1XTA3bEt1R16KGLQ1yPHY6b2g/image.png Ayatan treasures are items used as decoration. They can also be converted to Endo, a resource used to increase the level of mods. https://i.ytimg.com/vi/dcOsPK0mHTM/maxresdefault.jpg c.1) How to Obtain Ayatan Stars and Treasures Ayatan stars are obtained from any container from any mission type. Ayatan treasures on the other hand are obtained in two ways. First is by finding them as hidden items in a mission as seen here: http://i.imgur.com/f5H5QB2.jpg They don't spawn on every mission all the time. It is all based on luck. The second mission is by going to the Maroo's bazaar in Mars. Talk to her about Ayatan treasures and she will give you a specific mission for you to obtain one. In this mission, you have to complete an obstacle course with a time limit. If you fail to complete the obstacle you fail the mission, thus no Ayatan treasure. d) Other items
Here are other miscellaneous items you can trade: Crafted Derelict Keys Used to access derelict missions. Their blueprints are purchased in the in-game market with credits. Legendary Core Used to instantly upgrade a mod to max rank. Can be obtained as a very rare reward from finishing sortie missions. Riven Mods A rare type of mod that can only be obtained as a common reward from finishing sortie missions. Basic Focus Lenses Focus lenses are used to acquire focus. These are also used as a component of crafting greater focus lenses. They can be acquired by doing bounty missions in the Cetus node on Earth. Greater focus lenses cannot be traded. How to Trade
Now that we know which items you can and cannot trade, let us now discuss how you trade items. Finding Customers
There are 3 main ways to find customers, these are the trading chat, Maroo's bazaar and the fan-made website Warframe.market. a) Trading Chat
This can be accessed by pressing the default chat button T and navigating to the specific channel for trades. https://i.redd.it/79sqs3zeri0z.jpg It will be very confusing at first because people use tons of acronyms. These are the basic terminologies: WTS - Used if you "want to sell" something WTB - Used if you "want to buy" something WTT - Used if you "want to trade" something PMO - Used if you want the buyer or seller to "private message" you an "offer" price Unranked - Mod that has not been upgraded yet Max ranked - Fully upgraded mod Set - Full item parts including the main blueprint for a specific warframe or weapon Bp - Blueprint p - Indicates the price in platinum Ex: 5p = 5 Platinum b)Maroo's Bazaar
Maroo's bazaar can be found in the planet Mars. http://i.imgur.com/pJYxhM7.jpg Here you can set up your own shop or trade with other players selling their items. We'll discuss in detail later how you set up your shop. c)Warframe.Market
This is a fan-made website where you can post items that you want to sell or buy. https://steemitimages.com/DQmSfYF2R6MMxEXwcWX5G8Ux51vdqXMH1oXc7YvBYkvDLZU/image.png Executing Trades
a) Maroo's Bazaar
Selling
Once you're inside Maroo's Bazaar, press the default emotes/gears button Q. You can change it in the settings menu under the name "item pop-up." This screen will show when you press it: https://steemitimages.com/DQmQe6dCZR2Cvjbm6Rv5ot2m33mSzrXBjPj5rexdV6osZjc/image.png Click "Set-Up Shop" Now you can place the items you want to sell: https://steemitimages.com/DQmbqdvgntWHmmkEToNkV5zy9ytWGAxpvs3VM1yhZ3RfdLG/image.png You can only advertise 5 items at a time. Once you're done selecting the items you want to sell click on "Accept Items." Now you simply have to wait for someone to approach you and you enter into a trade screen. Ensure that your buyer is paying the correct amount of platinum you agreed on before you finalize the trade. Buying
To buy items in Maroo's Bazaar simply walk up to a person advertising an item you want to buy and press the trade button when the prompt shows up. The default button is E: https://steemitimages.com/DQmaNTjttQ9VPcwMoQQ8meTgXPovSGDBx9T8mR9CHHXEieM/image.png b) Trade Chat
Selling
After making a WTS post in the trade chat, wait for somebody to message you regarding that item. After you've agreed on a final price you may choose to either invite that person to your squad or have them invite you. Once you're in a squad, head to your clan dojo(or the other guy's it's your choice.) Once inside a clan dojo, go to the trading post and enter the trading screen from there: https://steemitimages.com/DQmbjC2ut5nGRFhAXEg38tRF9qu1W6RRkU7jLnmuoYdvZNk/image.png *dojo trading post* Buying
The steps are all the same except that you make a WTB post in the trade chat and wait for a buyer to offer you a price for it. c) Warframe.Market
This is by far the most recommended method because it is much more efficient. 90% of my customers are from the market. Another advantage of using the market is that since many players post the same item for sale, you can easily compare prices and buy the cheapest one. Selling
After registering an account in the market, click the "Place Order" button in the lower right of the website. This window will pop up where you type an item name, the price you want, and specific details relating to that item: https://steemitimages.com/DQmfPd5WSdaK2EPBRdSJf7kcKbnmCd4Cj8UvauFVsdp6w3T/image.png After that, just wait for a buyer to contact you in the in-game chat and follow the same steps in the Trading Chat method(minus the posting in trade chat of course.) Buying
Type the item you want to buy in the search bar. It will list the different sellers offering that item as well as their respective prices for it. Filter the sellers for "in-game" so you will only see sellers that are available for contact. https://steemitimages.com/DQmVU9zojQ3dAYnmPmt3SYxiYT6zHk6K198g8j1sPqm5GZ7/image.png If you can't find the price you want, filter for "all" and wait for that player to come online. Scroll over the "offline" tag to know how active they are. https://steemitimages.com/DQmVjwm9dzPuc1VznNF2ZshegYK4Bphu1qS5CzBeHbTbLSB/image.png Once you found an ideal buyer contact them by pressing this button next to their post: https://steemitimages.com/DQmQN5CtgUeTvGV27piWw8QbV3mXaaGa9egm3d8YcYGfUcB/image.png It will show you this message: https://steemitimages.com/DQmbXvzjKy9ppGXWLAL6ZQtX3gYgSVang7B3ix8GDfZCjtE/image.png Copy and paste that message into the in-game chat and wait for them to reply back. After that just follow the usual steps for trading. Note that a key difference in the warframe.market method is that you CANNOT negotiate the price anymore. *PS: You can also click "Place order" and make a "Want to buy" post but this is very inefficient as sellers seldom look at that section of the website.*

I will end the guide here. If I missed any detail or got some details wrong comment it and I will add/correct my post. Dogeking out. https://uploads.scratch.mit.edu/users/avatars/424/9680.png
