Quick Notes - Trading Ideas

• Momentum can be a result of nonlinearity/positive feedback due to algo trading: buy and sell orders induce more orders of their own kinds. Also, especially during market open, order regularities is a sign of algo in action. Can those be detected and exploited?
• Support and resistance levels, together with trading volume, provide useful insights. However, support and resistance levels (and similarly some other price patterns) are difficult to be quantified. Can neural network help?
• Support and resistance levels and volume data are more useful for securities that does not attract a lot of hedging investors (examples: commodities futures, mid cap stocks; counter-examples: ETF, some index futures).
