After creating an account and funding it, select a market to trade from the drop down and a quote duration by clicking on the appropriate duration you are looking for:
In this case the trader has chosen ETH/USD as the currency exchange rate to trade, and 1 hour for the quote duration. The time the trade is created, plus the quote duration is what sets the trade's expiration time (i.e. the time from trade initiation to settlement is the quote duration).
For a trade, hover the mouse on the right hand side of the screen so that a green bar (and not a red bar) appears to the right of the chart as shown below (A):
The height of the green bar (B) is the amount the rate will have to rise in order for your trade to make a profit. The cost of the trade gives the token amount you will pay to the market maker (C) and the quantity (D) is the multiplier of any price movement that happens in your favor, i.e. if ETH/USD were to risk $1, the profit of this trade would be 9.3771fox. (Note that C = B * D)
As you move the mouse left and right, you adjust the quantity of the trade, and under some market conditions the break even point will not be the same height as your cost, for example if there are multiple quotes available to trade for that time duration.
Trading a put is done the same way, except now there is a red bar that shows the amount ETH/USD will have to drop in order for this trade to make a profit.
After the time duration has passed, the trade will be settled and if the price has risen (call) or dropped (put) more than the height of the green (call) or red (put) bar, your trade will be profitable. Trades on Microtick are targeted to around 10X leverage, but under some conditions you may see considerably more (or less) leverage.
Once you have chosen the approximate quantity and cost you want, click the mouse and a dialog will pop up allowing you to fine tune the quantity and cost. You can then finish the trade, or cancel.
An example of a profitable trade is shown below. Here the trader timed the market well, and the trade maxed out the backing available which was over 10X the original cost of the trade.
