Based on NY close of RTH for US futures.

No need to test the obvious but yes I have done a lot of tests a few years ago and I prefer to stay away from long and big patterns since the average performance was negative even before commission and slippage.

Most studies have shown that market has short memory in the order of a few days. I would not expect big patterns to carry signal, only noise. I prefer price patterns between 3 and 5 bars. Look for Michael Harris and Price Action Lab. He is a master of price patterns and has devised a number of...

Not at this time. When you will be able to learn more the edge will be gone forever.

The most valuable book I have read after Market Wizards. Fooled By Technical analysis is a true gem. It offers step-by-step methodology for reducing data-mining bias among other things. An eye opener.

If you have to hit the car break hard your foot may hurt but you better do it. You are measuring the performance of the foot.

Your strategy is random trading. In reality you trade worse than random because some random traders make money - see this for example.

Quit trading yesterday.

TA is for suckers. Here it is best described as a method for pros to get suckers' money. Also reas Taleb's Fooled By Randomness for more improved thinking.

The guy who introduced me to trading has been doing that for 40 years with success. He never talks about his edge but he does calculations with an old HP calc and data tables from Yahoo finance. He has bought houses, expensive cars and much more with the profits. But he has told me horror...

Short speculators are gamblers and gamblers lose everything at some point. See this analysis that indicates a strong edge even if you hold just random long positions.
