A competitive scorekeeping ecosystem based on investor stock trade history and index analytics

Some new participants may see their first checkpoint display all zeroes for the tiebreaker factors. This is not an error—it is simply a timing issue based on how checkpoint spans are measured.
We recommend aligning your portfolio’s trade history to start on or before the previous checkpoint. This establishes the necessary baseline for the system to track accurately from Day 1. While the month-long Warm-Up is the ideal time to calibrate strategy, joining mid-challenge is never a setback; the app is designed for continuous experimentation and tactical refinement. By utilizing our weekly Friday-to-Friday checkpoints, participants experience a more modern, granular approach to performance. We believe that in 2026, there is no technical barrier to weekly transparency—only a legacy mindset.
Avoiding the “Blunderbuss Debut”
Checkpoint calculations always measure activity from Friday to Friday. When a participant creates a new portfolio mid‑week, and joins a challenge just before Friday’s close, the system evaluates a checkpoint period that began before their trade history existed. Because the portfolio had no recorded activity during that full Friday‑to‑Friday window, all tiebreaker factors evaluate to zero. In these cases, the app assigns the bonus of 10 points for that checkpoint.
This scenario is informally known as the Blunderbuss—a harmless first‑week outcome caused by joining too close to the checkpoint boundary. Participating in the Warm‑up allows your portfolio to accumulate a complete Friday‑to‑Friday history before the challenge begins. This ensures all tiebreaker factors populate normally, that the first official checkpoint reflects your actual portfolio behavior, and it avoids the zero‑value debut entirely.

Platform1 released Anonymous On Wall Street which provides PIX Challenge II and the new Market Race 1 on Android. Investors are using it now to experiment with stock portfolios and communicate freely.

History Does Repeat
Platform1 was inspired by the staff of a city newspaper who three decades earlier published their own stock contest. At one point, 498 portfolios from the newspaper’s readership were appraised often by a broker, and the final winner announced at the start of the new year. The contests began in ’88 right after the Crash of ’87 and lasted eight years – an astonishing success, and despite messy corrections of portfolios. Their readership simply found the experience fun and especially when their stocks beat the S&P 500.
Platform1 and the PIX Challenge Series gives it back to the investor, plus enough confidence and QC that makes stock performance enjoyable. The first PIX Challenge was closely contested for eleven months, when finally, in late March, Penny Saver kept the lead and finished with the outstanding score of 7355. Always at the apex was runner-up at 6680 (more information on our social media, below). Stock investors had managed their experimental or real portfolios for 52 weeks. They joined the challenge at any time, and updated trade history whenever personally convenient. Platform1 began delivering comparative results after the market closed on Friday, March 24, 2023. It’s currently up and running.
The PIX Challenge Series encourages plenty of time to relax and contact participants – anonymously. It is free to use, although some may subscribe to publish the data. Subscribers have the additional option to sponsor and create their own challenge. In any case, the platform ecosystem is advantageous, producing analytics that notably exclude the investor’s identity and portfolio value. It’s crucial to incorporate Platform1 software into a comprehensive investment approach, where the equity investor also consults with financial experts.
