Signal desk runs one rule. A stock has to be in a serious long term uptrend, it has to pull back, and it has to turn back up. Nothing about that is complicated, but each piece rests on an idea that is usually explained badly, so these pages explain them properly.

Everything here describes the system that is actually running. Where a page gives a threshold or a schedule, that is the real threshold and the real schedule, not an illustration.

• What is StochRSI?StochRSI measures how stretched a stock's momentum is, on a scale of 0 to 100. It applies the stochastic oscillator to RSI values instead of to price, so it reads the momentum of the momentum. A reading near 100 means RSI is sitting at the top of its own recent range.
• What does a StochRSI reading of 100 mean?It means momentum is as stretched as it has been in the last 14 periods, because RSI is sitting at the very top of its own range. On a monthly or annual bar that is rare, and it tends to last, which is why it is better read as a sign of strength than as a warning.
• How do you trade a StochRSI pullback?In three steps. A stock qualifies when monthly or annual StochRSI reaches the top of its range. It becomes armed when daily momentum falls to 20 or below. A signal fires when daily momentum recovers back above 20, which means the dip is over and the longer trend is still intact.
• Why read momentum on two timeframes?Because they answer different questions. The monthly or annual chart tells you whether a stock is in a serious uptrend, which changes slowly. The daily chart tells you whether right now is a good moment inside that trend, which changes fast. One picks the stock, the other picks the day.
• What do 13F filings tell you about institutional buying?Large US institutions must disclose their holdings every quarter in a filing called a 13F. Comparing consecutive filings shows whether a manager added to a position or cut it. Signal desk uses this to check that BlackRock, Vanguard and State Street are buying a stock rather than selling it.
• Why does missing data count as a failure?Because treating a missing number as neutral quietly turns every gap in the data into a pass. Signal desk does the opposite: if a check cannot be run, the stock does not get in. That rejects some good stocks, and in exchange nothing is ever admitted on the strength of a number nobody actually saw.
