The Calculation

The calculation is centred around 100. An index figure of >100 represents a bullish sentiment where more investors expect a rising market. An index figure of <100 represents a bearish sentiment where more investors expect the market to fall.

SERIX = ( % BULLISH TRADES - % BEARISH TRADES) +100

BULLISH TRADES

Number of trades on long instruments bought + number of trades on short instruments sold

BEARISH TRADES

Number of trades on long instruments sold + number of trades on short instruments bought

Example
 

Long instruments

Short instruments

Buy

300 trades

150 trades

Sell

200 trades

350 trades

Total

1000 trades

The further away the index figure is from the centre point (100), the stronger the sentiment.
