plots randomly generated price (closing basis) from LHS of the chart. Re-plots each time you scroll
-just a curiosity really; perhaps a lesson in seeing patterns where there are none; 'fooled by randomness' etc. -always anchors/starts from the real close of the asset on the visible Left hand side of the chart. -adjust ATR as you like (bigger = probably more reliable/realistic). -adjust ATRmultiple as you like (discretionary; basically how many ATR ranges above/below last bar's random close, will the maximum random value above/below be; default is 1.5x (arbitrary).
