Why You SHOULD Use Only Adjusted Price Data?

Unadjusted Adjusted
Examine the above charts. MTDL has issued a bonus (7 for 5) on the 27th, i.e. adjustment should be made to the historical data from the day before and backwards; price*5/7 and volume*7/5. Prepare for a disaster if you use unadjusted price data:
  1. On the 27th you might be shocked because the chart says that the price is falling down fast, early cut-loss might be in place.
  2. MA gives a wrong picture (it shows a steep downtrend, while sideways is the correct one), other indicators using historical data will also give a wrong picture (Stochastic, Williams' %R, CCI, etc.)
  3. The chart also says that support has been penetrated, while the correct one should say that support is far from penetration. All trendlines, support lines, resistance lines will be invalid.

Unadjusted price database definitly lead you to bad decisions
