Standard WPR oscillator implemented as a histogram rounding its values to the standard range:

• 1 — no rounding;
• 2 — all values from minus 100 to 0 divided by 2;
• 5 — all values from minus 100 to 0 divided by 5;
• 10 — all values from minus 100 to 0 divided by 10;
• 20 — all values from minus 100 to 0 divided by 20;
• 50 — 0, 50, 100.

For all WPR values less than minus 50, rounding occurs to the lower side, while for all RSI values exceeding 50 — to the greater one.

The following input is used for rounding in the indicator:
