calendar spread

Think of two market women who both sell umbrellas at the same price, ₦2,500 each. One promises to deliver hers in two weeks, the other in two months. If rain looks unlikely soon but you expect a proper downpour later in the year, you would rather hold the two month promise than the two week one, because the short one expires before the rain even arrives.

A calendar spread works on that same instinct, except it lives in the options market. You sell an option that expires soon and buy an option on the same stock, same strike price, that expires later. You collect a small amount from the option you sold, and you pay a bit more for the one you bought, so you spend a little money overall to set the trade up.

The whole idea leans on something called time decay. An option that expires soon loses its value quickly as the days pass, almost like a phone battery draining fast near the end. The longer dated option loses value much slower. So if the stock stays roughly where it is, the near term option you sold withers away nicely while the one you bought still holds most of its worth, and the gap between them can grow in your favour.

A Nigerian trader using a platform that offers United States listed options might do this on a stock like Tesla, selling a one month call and buying a three month call at the same strike, expecting Tesla to stay fairly calm in the short run. Someone in London doing the same on the London Stock Exchange through a broker would be running the identical playbook, just with pounds instead of dollars.

This is a strategy for patient people who think a stock will go nowhere dramatic for a while, not for anyone chasing a quick double. It is also not the sort of trade a total beginner should start with, since pricing options correctly takes practice and a broker that actually supports options trading, which most everyday Nigerian retail apps do not yet offer.
