Yuraz MCCH Calculation Indicator

Related: i-sadukey Digital Trend Filter - another powerful indicator for MetaTrader 5 traders.

The indicator calculates the percentage of growth or drop towards close. It is written using object-oriented programming and can be easily integrated into any expert advisor or other indicator.

Also recommended: J2 JMACandle - similar indicator with strong performance on MetaTrader 5.

The indicator calculates ch%, the percentage of change of the previous day's close.

It creates objects on a chart and is written in an object-oriented programming style.

Integration into other indicators or expert advisors is straightforward. You can estimate the code size when integrated into another indicator or expert advisor.

There are two lines:

cchmcyz chmc;

chmc.rchsay("eurusd",timecurrent()-86400*5,timecurrent(),5,16); // Calculate the current day's ch%

Object-oriented programming offers massive opportunities. Necessary classes are written, and then you construct...
