How to track Trump's trades yourself:
1. He files OGE Form 278-T reports with the Office of Government Ethics.
2. Each trade is listed as a range, from $1,001 to $15,000 up to $5 million to $25 million.
3. His August trades, all 517, were made public October 8.
4. Look up the price on the trade date. Compare it to today.
That's the whole system. We do it every time a filing drops.
