Continuing Indicator Line Into Future?

[KdonFX]

I was wondering if someone could give me some tips or point me in the right direction to continue the end of a moving average indicator into the future.

Basically what I want to do is get the slope of the indicator line for the last two periods and then draw the indicator going into the future with a straight line for that slope.

I think it will need to use the funtction to shift the indicator but I'm just not sure how I should get started.

Any help is greatly appreciate :)

Thanks.

Hello,

What you need is to calculate the variation between two points, and divide it by the amount of bars counted.

Change_per_bar = (Value_now / Previous_value) / bars counted;

That would give you an average increment or decrease by bar, and then you can draw the "future" line based on each increment.

However, the slope is a visual perspective and does not -and cannot- not apply here.

            color clr, bool ray=false){
    if (!Show.Objects)  return;                 #define WINDOW_MAIN 0
    if      (ObjectMove( name, 0, T0, P0 ))     ObjectMove(name, 1, T1, P1);
    else if (!ObjectCreate( name, OBJ_TREND, WINDOW_MAIN, T0, P0, T1, P1 ))
        Alert("ObjectCreate(",name,",TREND) failed: ", GetLastError() );
    else if (!ObjectSet( name, OBJPROP_RAY, ray ))
        Alert("ObjectSet(", name, ",Ray) failed: ", GetLastError());
    if (!ObjectSet(name, OBJPROP_COLOR, clr )) // Allow color change
        Alert("ObjectSet(", name, ",Color) [4] failed: ", GetLastError());
}
:
double ma2 = iMA(..., 2),
       ma1 = iMA(..., 1);
TLine("MAprojected", Time[2], ma2, Time[1], ma1, Red, true);

for indicators you can also use SetIndexShift to shift a buffer into the future.
