The QStick indicator is a simple n-period moving average of the price difference.
QStick = SMA(Period, (Close - Open))
QStick can be used as a simple replacement of candlesticks. Positive values of QStick indicate a prevalence of "white" candlesticks in the n-period interval, while negative values indicate a prevalence of "black" candlesticks.
The indicator may use different averaging algorithms. It should be noted that Phase type parameters for different smoothing algorithms have completely different meaning. For JMA it is an external Phase variable changing from -100 to +100. For T3 it is a smoothing ratio multiplied by 100 for better visualization, for VIDYA it is a CMO oscillator period and for AMA it is a slow EMA period. In other algorithms these parameters do not affect averaging. For AMA the fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power for AMA is also fixed on 2.
The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
This indicator was first implemented in MQL4 and published in Code Base on 20.02.2008.

A trend indicator implemented in the form of NRTR.Chande_Kroll_Stop_v1
An indicator of the trend power drawn in the form of a colored cloud.
Trend indicator, based on crossover of pivot level and its median.iBarShift
There are a lot of users who searched for iBarShift function like in MQL4. But this function is no more include in MQL5, mainly because MQL5 provides all necessary basic, low-level, functions to process such thing in a library.
