This can be subject to change. For example, you may have to get a Stalker at 18 if you scout a Reaper rush. Additionally, some build call for the Observer a little later, but I think this is too late. You need to be very careful against a quick 6-8 Marines and 3-4 Marauder push.
When you scout with your Observer, take a look at the enemy's unit composition. If you see a lot of air units, you are going to want to grab some Stalkers (rare). In this situation, throw down another 2 Gateways.
If you see an Marine, Marauder, and Siege Tank mix (most common), start building Immortals and Colossi. The more Marines you see, the more Colossi you will need. The more Marauders and Siege Tanks, the more Immortals you will need. Additionally, throw down another Robotics Facility to speed up unit production.
