I only day trade.Before entering any trade first thing I check is since how many days the stock is up or down and what was the previous days rsi(2),It will give a fair idea where the stock price is , whether overbought or over sold. Next before entering a trade whether long or short i check the current rsi for the particular price it will give a fair idea how much risk i am taking .I trade with intraday scanner, when the system shows some buy or sell signal , i cross check with the rsi(2) value to confirm the same. It is not a trading system, but will be useful to make trading decision.
