Bollinger
Bands
Bollinger Bands have several uses but for the mechanical trader
the primary use is price in relation to the upper and lower bands
as defined as overbought or oversold. Generally they are set at a
period of 20 with a standard deviation of 2.
Bollinger Band
overbought/oversold – a trigger that asks price to
reach a band to signal overbought or oversold
Example:
- If trend is bullish when price hits lower Bollinger band look
for a trade event
- If trend is bearish when price hits upper Bollinger band look
for a trade event

At this point we have covered several key trigger tools that the
mechanical trader could employ. The following are triggers employed
more so by discretionary traders. As stated before, the
discretionary trader may use their analysis to gather evidence that
a possible trade is setting up, and along with the tools mentioned
above, there are some additional tools we suggest.
