-<h4>Example 1: Use Market On Open Orders</h4>
-<p>In this example, we create an Market On Open order (MOO) to purchase 10 shares of SPY on July 1st, 2021 at 10:31 AM. The <code class="csharp">MarketOnOpenOrder</code><code class="python">market_on_open_order</code> method places a trade which fills when the market next opens. In this example it fills at 9:30 AM the following day. Market on open orders must be placed at least 15 minutes before market open.</p>
