📅 T+2 & Buying Power

Follow a trade from the moment it fills to the moment the assets are actually yours to use — drawn on a day-by-day timeline where the deciding boundary turns out to sit between the two sessions of T+2 rather than between two days. Four models cover the settlement cycle and why the morning of T+2 is still too early, buying power and the three reasons your balance is not the number you can spend, the multilateral netting that makes a two-day cycle necessary in the first place, and what happens on a settlement day when somebody is short. Each step lights up the matching line of Go and TypeScript.
