QQE MT4

QQE (Quantative Qualitative Estimation) MT4 Version by Roman Ignatov
Another indicator from MT4 to pinescript, from a google search i found the that the original author is unknown and its best used for volatile pairs /JPY
yellow line is a smoothed rsi,
red line "slow trailing stop" is the ATR smoothing with a 14-periods wilders smoothing function that is multiplied by a factor of 4.236
Also big thanks to BlindFreddy, i used part of his supertrend indicator to make it work
