Although for many this is not a topic they normally have on their radar, when we do Futures things can go wrong, and sometimes too wrong, so it's never too much to know what DCA is, which stands for Dollar Cost Averaging or what we simply call Averaging on this side of the world.
Not knowing how to do DCA in Futures, but still trying to do it, is almost always like throwing money into the fire to burn your account faster, but if you know how to calculate your Average Entry Price, DCA is your best tool to recover a trade that went against you.
