It is possible and it is very easy.

If you want to compare the Close prices, it means that you have to wait for the Close of the current bar. But when the bar closes, the new opens, so you are actually at the next bar Open and the Market price is that Open. In that case you are sending an Market order instead of Stop pending order.

We can use the Momentum indicator for an opening logic condition because
Momentum(p) = Close(t) - Close(t-p).

The strategy looks like:

Momentum > 0 means that Close > Close(t-4)
