Is it possible to enable/disable automated trading using EA?

<p id="isPasted">Here a revised version of this EA. It use your computer/VPS local time so you will not have to change the time for all your different accounts. It also use OnTimer() instead of OnTick(). OnTick was not working well. And finally it incorporate HH:MM. So you can close x minutes before the opening of a specific market.</p><p><br><img data-fr-image-pasted="true" src="data:image/png;base64,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" alt="File Type: mq4" width="16" height="16" border="0" title="File Type: mq4" style="-webkit-tap-highlight-color: transparent; border: 0px; color: rgb(0, 0, 0); font-family: Verdana, Helvetica, sans-serif; font-size: 11.088px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(244, 246, 249); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;" id="isPasted" class="fr-fic fr-dii fr-draggable">&nbsp;<a href="https://www.forexfactory.com/attachment/file/3756173?d=1601702583" target="_blank" rel="noopener noreferrer">Auto Trading_v2.mq4</a> &nbsp; 5 KB</p><p><br></p><p><br></p>
