EA opens trades from support and resistance levels (trendline — element from a toolbar) which were set by a trader. The direction is selected by the arrows, graphically.

Two options are available:

• Trade the move from the levels (arrows — up and down). If the open price is under the level, the EA will open the sell position when price crosses the level. The buy position has the opposite condition.
• Trade the crossing the levels (↕). If the open price is under the level, the EA will open the buy position when price crosses the level. The sell position has the opposite condition.

Levels have different colors, according to their angle. Level is “off” if inappropriate arrows were set. In this case level is thin. If you want to make a horizontal level, move its second handle to the left from the first handle.
