yes we can predict the future price move depending on the previous price because the price movement have some level of support and resistance. if the price get a strong resistance in a level then it will must face the resistance in this level and gone back when in bullish trend. in case of bearish trend the price will must get strong support in previous support level. actually we just can make a literature of past history but we cannot believe to history one hundred percent because the market always moving and moving again, we cannot predict it with history, it might can looping but it is safe if we use the correct analysis, not based on the history
