First: Put 2 Indicators in the same indicator window. I used ADOSC(15,60) and ADOSC(10,30). Make sure they are in the same space, so both lines draw on the same graph.

Next: Put the cursor over one indicator on a peak or valley and read what the value says on the right hand side. Do the same for a peak or valley on the other indicator.

Last: Scroll the graph left or right a little so that the graph redraws the scaling. Then look at the same peaks and valleys from the indicators. They will have hugely different values.

I had value go from 1000 to 12000. The value shouldn't change at all.

The scaling of the graph is affecting the actual value output of the indicator and it certainly shouldn't do that. This effectively means that trading on visual indicators could be quite broken.

Hi,
We weren't able to reproduce this, please make sure you compare indicator values for the same bars.

Maybe it is another MacOS bug. Scaling doesn't work on almost everything.

For example, draw a ray line on the chart as a diagonal support/resistance line. Then look at a 3rd reference point that is ON the ray line. Now start moving/zooming/scaling the chart. Almost always, the 3rd reference point is no longer ON the ray line. It may scale above or below the line.

If the ray line was represented by a slope constant and a start coordinate, I can't see how the scaling would affect it... but it does.

Look at the two posted screens, the time between 13:50 and 14:50. Screen1.jpg shows crossovers on the two indicators. Screen2.jpg shows NO crossovers. All I did there was move the view window, I didn't zoom or scale. My concern is if someone is trading on some kind of indicator crossover and the crossover isn't reliable, it is useless on the platform.

Error when scaling graphics.
The figure shows three indicators Stochastic. 2 standard indicator STOCH, and one CATSTOCH designed to speed up the calculation. The numerical values of the indicators STOCH (1000,200, SMA, 100, SMA) and CATSTOCH (1000,200, SMA, 100, SMA) coincide. On the panel graphics are different !!! Note the horizontal level line 80 is also different (black and white).
