Frequently Asked Questions

Q: What is the significance of the patterns and trendlines?
A: There is a wealth of information you can learn about trendlines and chart patterns, such as this. They are among the oldest concepts in technical analysis, but they are also the most subjective and difficult to identify. There is no formula you can just plug in and get the results. Most require human eyes and experience. However, with the semi-heuristic algorithm I have developed, it is possible to identify these patterns and lines with computer. There are some false positives so you still need manual confirmation, but this saves a lot of time and effort by not having to scan through all charts manually.

Q: What exactly are trendlines?
A trend line is a bounding line for the price movement of a security. A support trend line (or a bottom line) is formed when a securities price decreases and then rebounds at a pivot point that aligns with at least two previous support pivot points. Similarly a resistance trend line (or a top line) is formed when a securities price increases and then rebounds at a pivot point that aligns with at least two previous resistance pivot points. In other words, bottom lines are formed by joining a series of bottom points, and top lines are formed by joining a series of peaks.

Trendlines are considered by many expert traders and investors as the single most important tools in technical analysis. However, unlike other indicators of Technical Analysis, it does not come with a fixed formula, but require human eyes and brain to draw the best fit line across a series of bottoms or tops. It is still very much of an art form. If you are looking for a particular trendline pattern - such as Resistance breakout, the tasks of drawing trendlines for all stocks on the market becomes tedious if not impossible. Screenulator solves the problem for you.

Q: What are the trendline colors?
Line colors:

Pink: Closest bounding support and resistance lines
Yellow: Recently penetrated lines
Green: The line that has been penetrated for a long time, about to be removed from the chart
Grey: All the other lines

Q: How frequently do you update the screening results?
A: Screener results are computed twice daily: once in the morning 11 - 12 am, and once at market close (after 5 pm). The mornig update time varies depending on market volatility. I want to make sure market is reasonably stable before running pattern screeners to get more accurate results. Same day results are only available for paying memebers. See Membership Benefits for details.

Q: Which symbols and how many symbols do you screen?
A: As of December 2013, about 14000 symbols for US, Canada, Australia, NZ, HK, China, India (NSE), Jakarta, Singapore (SGX), Europe, London stocks are supported. As well as selected ETFs. Stocks supported must have minumum price of $1 and adequate liquidity. This site is not about penny stock picks! If you want your market supported, such as FOREX or other world markets, please drop me an email. The program works on any traded equity from commodities to FOREX to traditional stocks. But for now my time and budget only allows me to use these data. They are sufficient to generate a good amount of trading opportunities. But if you are interested in applying my screener on other markets and symbols, just send me a request Request page

Q: What market data are you using?
A: Real time market data from yahoo finance.

Q: When I search for a symbol, why can't I see the quote?
A: It is because this is not a quote site. If you just want to check stock quotes, there are hundreds of other sites dedicated for that purpose. The search for symbol function searches through all pre-defined filter results, and find matching symbol in their corresponding filter category and date.

I have developed a computer algorithm to detect all possible trendlines to aid your analysis. Not all the trendlines are correct, or useful. every trader has his own opinion on which trendlines are should be, and some trendlines are more important than others. Screenulator show you all possible trendlines including ones you could possibly have missed.

Q: How do I know buy or sell recommendations on a stock?
A: Again this is not a stock pick site. I do have offer investment advise. You should do your own research with the help of powerful tools such as screenulator and learn the knowledge of technical analysis.
