when these yahoo prices w/o bonus adjusted are imported into metastock....
can indicator produce wrong buy n sell signals????
which chart is right for analysis bonus adjusted or w/o it???
Yes, indicators will produce large buy and sell signals, however only until a particular no. of sessions, say for 14 days if you use ADX 14 setting. If the adjustment has been missed 50 sessions ago and you are calculating RSI 15, you will get correct value.
Ideally, you should use a "clean" database for analysis - which means its is adjusted for corporate actiosn like dividends, bonus, split, consolidation, swap, ticker change, etc etc.
