Note: all timings in the table below are denominated in UTC

There are opportunities around the clock, as different markets open, you can trade binary options contracts based on the different currencies. Note: December 25th — 27th and January 1st — 3rd are holidays when the markets are closed.

How to Trade Forex With Binary Options on Buffer?

To trade FX with binary options on Buffer Testnet, you will need to:

Step 1 — Setup Arbitrum Goerli Testnet on your wallet

To add the Arbitrum-Görli testnet to MetaMask, click the network button at the top of your wallet and change it to “Arbitrum Nitro Rollup Testnet.”

If the Arbitrum Nitro Goerli Rollup Testnet is not listed on your wallet, click on “Add Network” and enter the following Arbitrum-Görli testnet parameters:

Step 2 — Add ETH Goerli to your MetaMask

Click on the ‘Faucet’ tab and then click on the “1. Claim goerliETH from Goerli faucet” link under the ‘Claim TESTNET AETH’ tab.

You can use any one of the three faucet options given to claim your görliETH:

#1: Using the Goerli faucet:

  • Requires signing up/logging in using an Alchemy account.

#2: Using the Goerli Mudit faucet:

  • Requires users to make a tweet using the tweet template linked on the faucet’s page under the “How does this work?” section.
  • Users must also paste their Ethereum address into the tweet template to receive funds using this faucet.

#3: Using the Paradigm Multifaucet:

  • Requires users to sign in with their Twitter accounts.
  • To successfully receive funds using the faucet, the user’s Twitter accounts should have at least 1 Tweet, 15 followers, and be older than 1 month.

For this guide, we’re using the first option — the Goerli faucet to claim görliETH.

Bridge Goreli ETH to Arbitrum ETH

Once you have claimed your Goerli ETH, go back to the “Faucet” section on Buffer Testnet, and click on the “2. Bridge GoerliETH to AETH” button.

You will be directed to the Arbitrum Bridge. Connect your Goerli L1 ETH to Arbitrum’s Goerli Testnet on layer 2 by connecting your wallet to the Arbitrum Goerli bridge.

Step 3 — Claim Testnet USDC

In order to claim your Testnet USDC tokens, by clicking on the “claim USDC” button on the Faucet page

Confirm the transaction. Once processed, you will have 500 Test USDC in your wallet.

Step 4 — Choose the forex market you want to trade with

To open a position, choose an asset from the asset drop-down menu on the top left-hand corner of the ‘Trade page’ or from the list of “Watched Pairs section.”

Step 5 — Choose the desired timeframe

You can choose the Timeframe from the “Select Duration” box on the right-hand side of the dashboard.

Step 6 — Choose your Trade Size

You can choose your USDC investment in the “Trade Size” box.

Step 8 — Approve the contract before opening a position

Once you click the approve button, a pop-up will appear asking you to approve the contract.

Step 9 — Choose the direction — Up or Down.

Once you decide to open Up or Down positions, you are ready to open a trade. Once a position is opened after you approve the transaction in Metamask, you will need to wait until the end of the expiration time to receive the result.

What’s next?

While you test out the fx markets, we have a few tasks in the pipeline, including the launch of our leaderboard, the much-awaited Buffer NFTs, and the deployer contract distribution.

Additionally, due to the increasing complexity of our codebase, we opted to audit our contracts via Sherlock, which is still in progress. We should get the results in the coming weeks. Once the audits are complete ensuring the new code is sufficiently analyzed, we will be ready to go live on the mainnet.
