The script highlighted in this chart is what I call the slope changes of the CSM trigger lines,. The trigger lines refer to a special non-lagging moving average derived off currency indices that will act as the potential signal to enter into positions if the rest of conditions as part of the CSM strategy agree. The script acts as an inflection point when an imbalance of flows in currency indices are expected based on the slope of the CSM trigger lines.
When the signal occurs, an area will be colored in green (long) or red (short), depending on the trade direction, of the quality of the signal is sudden in nature. If the slope change doesn't not happy in synchronicity but there is a delay of 1 candle in either index, the color of the signal will be in blue (long) or orange (short).
