Our Probabilistic Prediction

We train models based on the identified causal predictors and run them, with each model predicting a set of possible outcomes for the time point 6m away. The sets of possible outcomes are then aggregated.

Goodness of Probabilistic Prediction

Test of hypothesis that a sample of the realised probability level is uniformly distributed between 0 and 1 (whitepaper), using significance level 0.001 for the p-value. The user is free to use another significance level e.g. 0.01, 0.05 for the test.

Trades

Each model casts a single vote on the likely direction of change. If a trade is executed, the size, in terms of the number of shares or lots, is proportional to the majority vote, and the trade is kept open for the duration of the forecast horizon, which is 6m. This exercise is repeated every day.

The position for the next day, averaged over the sizes of currently opened trades, is as follows

	% Up	% Down	% Undecided
