discontinuous buffer in custom indicator

[Kittamet Sirinyamas]

Hello everyone,

As we know that buffer value is calculated from price series such as moving average,rsi. which these indicators have continuous value.

What if the calculated value is not continuous like following image (blue line). What data type should the buffer store in the gap range?

Thank you very much

For MT4 I use:

1. One buffer has the value, color set to CLR_NONE so not shown on chart, (but in data window and pop up.)
2. Two buffers, one color each, with SetIndexLabel(i, NULL) so they don't show in data window.
3. Then you need to connect the lines on color change. downBuffer[i]=value[i]; if(downBuffer[i+1]==EMPTY_VALUE) downBuffer[i+1]=value[i].

Fill the gap with the value of the constant "EMPTY_VALUE"!
