body: <p>I cannot use the input.bool command in pine script V5. If the input is true, the following commands will work or not, how can I do it?</p>
  <pre><code>bak = input.bool(true, title=&quot;True or False&quot;)
  
  len = input.int(defval=13, minval=1, title=&quot;Length&quot;, group='Ema', confirm=false)
  src = input(close, title=&quot;Source&quot;, group='Ema')
  offset = input.int(title=&quot;Offset&quot;, defval=0, minval=-500, maxval=500, group='Ema')
  out = ta.ema(src, len)
  plot(out, title=&quot;EMA 13&quot;, color=color.blue, offset=offset, linewidth=2)
