Solana Build Night 3: Position Sizing and the Trade Ledger

​Open trades overlap in time, and a strategy has to count them together and size each bet from how confident it is. Tonight is a student-led build night on the two pieces of bookkeeping that decide whether a strategy holds up: turning confidence into a capped position size, and keeping a trade ledger that records every decision.

​We start with a short talk, then a demo tour: a sizing curve with caps, overlapping trades counted together, an append-only ledger replayed row by row (including an oversized trade that the risk check refuses, with its reason), and an equity chart before and after a change. Token balances and price impact are read from real Solana data.

​Then you extend the sample sizing code in your own project: add a limit, a cost, a drawdown halt or a different sizing rule, and chart the result. In the last 15 minutes you freeze a working commit and write a restart note for the break.

​Reads use public mainnet data; every write is devnet only; no real funds. Results are simulated on recorded data and are not advice. Beginners welcome, with a task for every level.
