This script is intended to help the viewer identify potential turning points with momentum "headwinds" or "tailwinds" with a visual que at the bar level. The presence of arrows indicates that the TSI indicator is either "curling" up under the signal line, or "curling" down over the signal line. This can help to anticipate reversals, or moves in favor of trend direction.
Multiple script overlays can be used for "Multi-timeframe analysis" by altering the "resolution" feature.
eg: Viewer could enable 2 "Arrow" scripts while watching the , and setting one of them to indicate weekly conditions. This can help identify prevailing trend strength when using smaller timeframes.
