The names are just variable names and don't really have any meaning as such. Programmers will usually choose variable names so that it's self explanatory what kind of value they're supposed to hold. Looking at those two it seems the programmer has chosen to add the suffix c to the current bars variable and p to the previous bars variable.
hey man got a question, I have an indicator that a friend gave me that I have been demoing for a couple weeks now and love it. Short explanation, an arrow will show up on my charts telling me to which way to play the movement. Using it on 30m charts so it doesn't come up too often. Is there a way to make it when the arrow shows up for the long position it will close out my short position and go long, or if there is no short position just go long. Also vice versa with the short signal?
I didnt see an edit button so here is the code. It doesn't seem as if it would be too difficult just to add in the buy or sell code. This is from the zigzag code. Free ind.
Code:
#property indicator_chart_window
#property indicator_buffers 1
#property indicator_color1 Red
//---- indicator parameters
extern int ExtDepth=12;
extern int ExtDeviation=5;
extern int ExtBackstep=3;
//---- indicator buffers
double ZigzagBuffer[];
double HighMapBuffer[];
double LowMapBuffer[];
int level=3; // recounting's depth
bool downloadhistory=false;

Thank you in advance
Look in the metaeditor help file at the iCustom function.
I have seen your name all over the forum as you are kind enough to help people mostly.
I would really appreciate if you could post the indicators you have on the chart you posted. Also I am looking for the ATR osc to be displayed on the main chart. Would you please tell me how to do that or provide me that osc as well please?
thanks

This one simply writes symbols as comment (like on picture)
