A computer is required

This assessment is a live trading simulation. It needs a large screen and a mouse: you will be reading two price charts and placing orders under time pressure. It cannot be completed on a phone or a small tablet.

Strategy presentation

Before the tests, watch a short live demonstration of how our operators work.

At Sigma Dynamix, operators do not analyse the market: our systems do. When conditions match the firm's strategy, an authorization signal lights up. Your job is to execute — enter in the allowed direction, quickly and consistently. Every position is protected by an automatic 70-tick trailing stop.

Taking every signal is mandatory. Your evaluation compares you with other operators on the same signals, so a skipped signal cannot be scored and counts against you.

Our strategy works with a buy and a sell on every signal. Each authorization requires two entries from you: one BUY and one SELL — opened at the same time, or one after the other.

The buy must be placed on a dip, the sell on a push higher. What makes the strategy profitable is the spread between your two entry prices: the higher your sell and the lower your buy, the more you make — whatever the market does afterwards. So never chase a rising market when you buy, and never chase a falling one when you sell. Always wait for your price.

The demo replays a real NQ market moment and shows two examples — one with both positions open simultaneously, one taken sequentially. Watching it in full is required before the tests.

Did you understand everything?

You can rewatch the demo if anything is unclear — otherwise, continue to the trading tests.
