BUY GUIDANCE: Never buy before 3PM (for positional trading). I have been burnt many times over. Try to buy between 3:15 - 3:30PM, later the better.
SL: Depending on your risk appetite: Below Weekly BO Candle / Below Daily BO Candle / 50% of Weekly BO candle / Below 20DMA TGT: After a 10-15%+ vertical move, breakdown of 20DMA (on a daily close basis)
SELL GUIDANCE: Selling in Profit: Sell earlier in the session when the prices are higher, around 11AM.
Selling at SL: Give your stock a chance to recover by end of session. If it doesn't recover, sell anywhere between 3:00 - 3:30PM.
Note: The breakout levels are derived from the weekly line chart which are respected by smart money much more than candlestick levels.
Note: I reserve the right to be wrong.
