PR Summary

Low Risk
Low risk: a single additional filter on the dex_trades source reduces the input dataset, mainly affecting price outputs for tokens predominantly traded via launchpads.

Overview
Updates ton.prices_daily (ton_jetton_price_daily.sql) to exclude project_type = 'launchpad' trades from the ALL_TRADES CTE, preventing launchpad activity from influencing daily jetton price derivation.

NULL project_type rows unintentionally excluded by filter

Medium Severity

The condition project_type != 'launchpad' will also filter out rows where project_type is NULL due to SQL's three-valued logic. When comparing NULL with any value using !=, the result is NULL (unknown), causing the row to be excluded from results. If the ton.dex_trades source contains trades with NULL project_type values, those legitimate trades would be unintentionally excluded from price calculations. Using project_type IS DISTINCT FROM 'launchpad' or (project_type IS NULL OR project_type != 'launchpad') would preserve NULL rows.

project_type can't be null in our case -- it is controlled by our datalake which uploads ton.dex_trades data to Dune

Any updates? This is very urgent @tomfutago
