Intelligence that works for you

What the engine does.

01

The model

About 800 decision trees trained on eight and a half years of S&P 500 data, the 2020 crash included.

02

50 measurements a minute

Price against moving averages on M15 and daily, the decline from recent highs, volatility versus normal, RSI, stochastic, CCI, Bollinger, hour, weekday and spread.

03

Selective entry

Most dips are let go. The engine keeps out when the answer is no, and shows you the decision on the chart.

04

Targets that grow with depth

Baskets of up to eight steps where the profit target grows with depth, instead of closing deep baskets at the same distance as shallow ones.

05

Guards

Equity protection at 50% in the preset modes, margin brake, spread guard, state saved across restarts: a basket resumes after a VPS reboot.

06

Local only

Runs entirely on the terminal: no DLL, no external connection. Hedging and netting accounts.

The star. Altair, the brightest star of Aquila, the Eagle. One of the three stars of the Summer Triangle.

Put to the test

Tested. Then traded in public.

  • Each release is checked against a reference engine trade by trade.
