Indicator XFisher_org_v1 provides alerts and sends email and push notifications when the main and signal lines intersect, accompanied by a change in the color of the signal cloud.

The indicator uses the classes of library SmoothAlgorithms.mqh (to be copied to <terminal_data_directory>\MQL5\Include). The use of the classes was thoroughly described in article Averaging Price Series for Intermediate Calculations without Using Additional Buffers.
