If the stock does not have very high liquidity (daily avg volume is less than 20000) then is it possible that the rules of candlesticks may not work always (considering stocks that have high liquidity are those stocks where big institutions are invested into and any move by them can influence price behavior and also assuming that big players will definitely apply some form of analysis before making a move)?
For stocks which are very illiquid and where prices can be influenced by few should be ideally avoided for applying technical chart patterns on them as anyhow chart patterns wont be smooth and inconclusive.These stocks should be approached with fundamental analysis or with news which effect individual company in particular.
