Instructions for creating advertising orders

Posting process:

  • Step 1: Click Create Ads.
  • Step 2: Ads page appears (e.g. Sell BTC). Depending on your needs, choose Sell or Buy. For example, select “Sell” and the type of digital asset as “BTC“.
  • Step 3: Price. Select price type, (e.g. choose fixed price). You can set prices as you wish or market prices.
    • Fixed price: price decided and set by the seller. For example, 1 BTC = VND 100,000,000 and regardless of whether the market goes up or down, the seller still expect to match the order at this price.
    • Float price: is the Reference Price of the Exchange x the margin set by the seller. Example: If the reference price is VND 80,000,000 and the margin is 5%, the price displayed on T-Rex will be VND 80,400,000 when the price goes up to VND 100,000,000, with margin of 5%, your displayed price on T-Rex is VND 105,000,000. However, if you want to sell faster, you can enter a low  margin of 1% or 2%.

Notes: The reference price of the T-Rex  is the price calculated based on Bitstamp Exchange

  • Step 4: Enter the unit price of 1 BTC and the number you want to sell
  • Step 5:Depending on your needs, please fill in the minimum/maximum amount that buyers can buy.
  • Step 6: Payment method. You can choose which bank you want to display to buyers. If you want to add or modify, you can click the “Add New” button to set up the bank, beneficiary name and account number.
  • Step 7: Post Ads. This is the last step. You must click the “Create ads” button to complete the ads creation.
  • Step 8: Check your ads on T-Rex. Your created advertising order will be displayed on the T-Rex, you can check it by clicking on “Orders” in the upper right corner of the screen to see if the transaction order has been confirmed by T-Rex and posted on OTC Exchange


The process is simple and easy, please pay attention when you enter “Price“. We do not encourage the maker to exaggerate the price when creating the ads, so please double check the “Price” when creating ads.

Advertising standards

  1. Ads arrangement: Prioritized advertising prices and creation time. Example: Sell of 1 USDT at a price of VND 23,000 is arranged before VND 25,000; but if there are many advertising orders created at the same price of VND 24,000, the early ads creators will be listed at the top.
  2. Edit ads: You may optionally edit the posted ads, and note that such revision will affect the existing order of priority on T-Rex OTC.
  3. Cancel ads: Ads will only be canceled when it is canceled by you or fully traded.
