Alpha Trading Signals

Every day ORTEX identifies alpha-generating opportunities. These are identified through rigorous analysis and validated through back-testing. The Alpha trading signal will tell you how much return has historically been made and the optimal holding period and relative success of this signal in the past. ORTEX back-test data sets in infinite combinations and bring you the highest-ranked signals across over 50,000 stocks every day. These signals are the ones that are most likely to happen again and produce the highest return in the shortest time. ORTEX Alpha signals are split into five families Short Squeeze, EPS, RSI, MACD and Company Events. Some of these signals families have multiple types. The different types of signal look at different aspects of the metric that is the main base for that signal.

Trading Signals Table

These shows all the recent signals in the stock you are looking at. Per default the table is sorted by date, with the most recent on top. You can click the table headings to change the sorting and also filter the table with the text boxes in the header or the sliders.

The type of Signal that has been fired. ORTEX Alpha signals are Short Squeeze, EPS, RSI, MACD and Company Events

EPS – There are three types of these signals, they are all based on changes in analysts EPS estimates but the three different types look at slightly different perspective of this. 

Short Squeeze –comes in Type1, 2 and 3. They look at slightly different aspects of how to detect a Short Squeeze, considering everything from Short Interest, Utilization, Cost to Borrow and the Stock Price as well as the rate of change in these.

RSI  – Comes in 3 different types which looks at different aspects of RSI. They are all fired when an extreme relative level is triggered that has historically produced a strong and predictive subsequent move.

MACD – This signal is based on MACD, it looks at multiple ratios over multiple time periods and fires when an extreme relative level is triggered that has historically produced a strong and predictive subsequent move.

The average mean return that the signal has historically generated.
