The classroom empties after the Thursday recap, and students go back to apartments in a city that is already dark. New York will open while rice is on the table. If your plan is to 'see what NY does,' you will see whatever the last five minutes suggested.
At 16:30 ICT, London has already shown its first impulse and often its first fade. That is the hour we ask you to write four lines, not to open a fifth timeframe.
Line one: where is the four-hour swing, in words, not in a squiggle. Line two: did London accept outside the Asian range or only probe it. Line three: the zone you will still respect if New York spikes twenty pips through it. Line four: the time you will stop looking — we suggest 22:30 ICT unless you are a night-desk trader, which most students are not.
Bangkok’s clock is a constraint, not a romance. You will miss some New York reversals because you were asleep or on the BTS. The classroom is not trying to make you a twenty-four-hour participant. It is trying to make the hours you do sit in front of the chart count as reading rather than as companionship for the candles.
If you cannot write those four lines at 16:30, you are not ready for a New York decision. Go back to the daily. That is not a moral failing. It is the same advice we give in week two when someone wants to trade the 23:00 spike because a friend in another timezone called it obvious.
