Ensure that your personal account is funded before proceeding to make a trade. You can fund your account by making a deposit. The first step in making a trade is to select your choice trading pair. Go to the black bar menu – you can find it at the upper left corner of your account. Then click on the trading pair. Click on your choice trading pair option. If you click on BTC/USD for instance, it means you can only trades for the selected trading pair – BTC for USD or USD for BTC. Thus, you will not be permitted to trade for other pairs, such as EUR for BTC or BTC for EUR. To trade with this pair, you will have to select them as your choice trading pair option.
