SR Trend + Stoch + Volume

Further continuation of my Support-Resistance breakout Strategy.
Now it uses Stoch and Volume for trend change identification. SR levels are plotted by the old algo.
Main purpose of this script is trend swings identification additionally to position, mainly it will show trend swing (bgcolor) not in position state to accomplish positions.

Main options:
- timeframe - defines length of MAs used.
- stoch levels - for overbought/sold levels identification.
- plotting SR lines - first support/resistance = stoploss, first support/ressistance = position enter.

For now, it made as study.
