yes, that would be better

because that means I would be able to buy more shares

But I am bad at charting, and I am bad at predict the market. 

next time I will add slowly and be more cautious. when holding cash, its good to see market drop :)

Warren Buffett: "If you expect to be a net saver during the next 5 years, should you hope for a higher or lower stock market during that period?"Many investors get this one wrong. Even though they are going to be net buyers of stocks for many years to come, they are elated when stock prices rise and depressed when they fall."This reaction makes no sense. Only those who will be sellers of equities in the near future should be happy at seeing stocks rise. Prospective purchasers should much prefer sinking prices.
