It's a shame, don't try to make excuses and find solutions...

Trading in futures contracts means that you are agreeing to buy or sell an asset (like gold, oil, currencies, or even stocks) at a specified price today, but the delivery and payment will be in the future, on an agreed-upon date.

The basic idea:

You expect that the price will change in the future (either rise or fall).

So you open a futures contract based on your expectation:

If you expect the price to rise, you buy a futures contract (long position).

If you expect the price to fall, you sell a futures contract (short position).
