The Arrows shows in Chart is Zig-Zag indicator (can find in Google). Looks repaint but No repaint can found here:
http://www.pointzero-trading.com/FreeMetatraderDownloads/view/14 but it backpaint
Other indicator is Support and Resistance means it show Pivote, R1, R2 R3 or S1, S2, S3 and can easily find in Google
Another Indicator that move down is Trend Channel Indicator but you can find or download True Trend Indicator
According to my view, Overall, this is custom Indicator and can made by any normal person, nothing special
Good Luck!
