bro I trade lot of stuff like stocks, indices F&O and currencies. i have read a lot about central banks controlling the directions of currency like JP Morgan who basically make the market in currencies so I generally avoid large positions in currencies. but the main thing I am concerned about is indices. You can justify TA in stocks but in indices it puzzles me. Basically I trade indian indices nifty and banknifty and tried to understand S&R in them. I observe that whenever nifty50 is near to a major support in 5 min TF, a major weightage stock is also near its support or a number of less weightage stocks are near their support. Howz that possible? its only possible only when indices and stocks are systematically managed by some institutional or exchange algos. or maybe institutions defend the level by some algos so as make people go in a particular direction they want them to go. or may be due to market makers hedging index f&o with etf and hence arbs make the constituents to change. Its very puzzling. I know general people don't bother about these, but these questions puzzle me a lot. All these concepts can enhance our interpretation of markets and better allow us to anticipate future moves
