In the OnCalculate()function, modify the CopyBuffer()function to copy all available RSI values (up to rates_total ) into the Rsi1Buffer. This will ensure you're copying all the relevant data.
After copying the buffer, loop through the remaining values in Rsi1Buffer(if any) and set them to EMPTY_VALUE . This ensures that any remaining values beyond rates_total are not plotted, preventing unwanted lines.
Remove the Rsi1Handle variable from the global scope and declared it inside the OnInit()function. This ensures that it's properly initialized.

thanks a lot. its so helpful;
do you know how can i set default value to buffer. i want set default value empty-value to buffer and don't use loop.
Wrong! It must be global as to be remembered. It must be properly initialized in OnInit.
Perhaps you should read the manual, especially the examples.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick/OnCalculate (after the indicator has updated its buffers), you use the handle, shift and count to get the data.
