Thanks for that chart. I'm going to investigate using RSI to determine if I should trade longs if RSI>50 & trade short if RSI<50. That is, us RSI to help me "trade the trend", With stops, of course.
MM: Here are three mechanical buy/sell systems for you to look at. All have been back-tested as big long-term winners on the INDU. I'm wondering if they back-test as well for the Naz?
#1. EMA-5
Buy/Cover the index at the close when close goes above PREVIOUS DAY's 5 day EMA
Sell/Short the index at the close when close drops below PREVIOUS DAY's 5 day EMA
2. Advancing Issues
Buy/Cover the index at the close when when today's Advancing Issues moves above PREVIOUS DAY's 3 day SMA of Advancing Issues
Short/Sell the index at the close when when today's Advancing Issues drop below PREVIOUS DAY's 3 day SMA of Advancing Issues
3. Declining Issues
Buy/Cover the index at the close when when today's Declining Issues drops below the PREVIOUS DAY's 2 day SMA of Declining Issues
Sell/Short the index at the close when when today's Declining Issues rise above the PREVIOUS DAY's 2 day SMA of Declining Issues
Note: None of these has a huge percentage of winners, but the aggregate $$$ earned are fairly impressive. Assuming each method were begun with $100 in 1900, all trading was carried out in the DOW 30 Index, all money was reinvested, and no taxes or transaction costs were paid, the methods would have yielded, as of 2001, the following:
