more on bollinger

i've been using bollinger for a long time to trace out potential movement of stocks or indices. this is because bollinger takes into account volatility as well as moving averages.

for example: a couple of days ago, STI surged up many many points, over 70 plus points and closed there at its high. that broke the upper band of the bollinger band indicator. the next day, the index gapped up close to about 40 points, now you won't expect the index to surge up again don't you? thats pretty absurd. a good indication to short at that point would be when the index started to drop 5-10 points. good to short.

nonetheless, the prices are still above the band, so we may see a few more days of red. simple logic. the surge caused many short term investors to cash in on their positions. selling pressure builds. short sellers then take over to further facilitate the liquidity of the transactions, pushing prices lower.

i don't know how far it'll drop. but my guess is that if it goes low, first point to look at is 2300. not that low, i know.
