Quick guide:
The 2Serpents indicator shows the current currency strength and ranges from 0 (minimum strength) to 9 (maximum strength).

If 2Serpents value is higher than 6 the currency may be overbought, if lower than 3 the currency may be oversold.

eg: If EUR is overbought and USD is oversold, a SELL position on EURUSD should be open.

If the two 2Serpents currency strength values are similar and both between 3 and 6, then the current trend is confirmed and no major trend change should occour.
