Viktor_k67, Thanks for your comments. Exactly I did my best to start with an extremely simple languaguge aqlang but the implementation of it took quite a bit of effort and fun. It is not perfect. It is built with a database optimized to work with aqlang programs. Now it can handle multiple...

If you were a good computer professional, you would have understood what I am talking about when I mentioned about all those terms about performance optimizations, database, languages, etc. Google the Dragon Book and The Whale Book. You will know a bit. If you were a computer geek or earned a...

I did not check this thread for the past few weeks. Thanks for the above few feedbacks. Stock fetcher and free chart Geany seem interesting but not the same tool I am working on. Aqtools is designed more for customization of indicators and filters of interest on any user defined watch list. It...

I use least square regression to calculate slopes for a given period. That given period is any number of points of your interest.

Out of curiosity, I checked a few penny stocks, COPY and ANDR. CEO at ANDR earns 342K but CEO at COPY earns 32K. CFOs at the two earn 160K annually. Both have less than 20 people. Why are these stocks still publicly traded? Many other penny stocks are similar and ridiculous.

I am in the middle of coding adjustment of historical quote. I am trying to understand what is the proper way to deal with stock split and dividend payout. It seems not really simple as it looks. I think it is ok to treat stock split proportionallly for previous prices and volumes. But I am...

More than 12% at high. Will go higher regardless of fundamentals then come down together with the whole market. No one really knows the timing.

Good tools are also very helpful to analyze historical and realtome data and to help manage your trading. But be ware of many traps there in so-called back testing because no where you can get quality data for your system otherwise composing your own from tick data to suite your own need.

Read my post again. You will see the goal is not for any return. I do not care someone gains or losses in whatever market. You do not need any tools to find your holy grail if you are smart enough. The gaol is to make an open source free software tool that does some TA in a better way or a new...

Agree. a program is useless in trading without quality data feed. Well, I will take a look at NiniTrader program. But for TA, either offline or online in real-time mode, I want to have a tool that is very flexible. The goal is not to replace any of trading systems or programs, but to assist...

Thanks for telling me more data sources. I have been downloading eod data from Yahoo and collected some 1 min intra-day data from other sources. The quality of raw eod data from Yahoo or any other places has a big issue of bogus low/high due to out-of-band trading or other reason that will...

Hi, I have been looking around but never found a good technical analysis software package that can satisfy my need. I am a software engineer. I decided write a tool myself. I intend to make this tool as an open source software, so everyone will enjoy for free. This is one of my hobby...

I was surprised that someone sent me PM asking me how I am doing in trading after a few years since I posted quite a lot of daily trades a few years ago in a series of experiments of trading ideas. Well, to be honest, I see trading is very hard. I still not yet make it. It is hard to beat my...

Interesting to know this. I see a lot of these ridiculous highs and lows a lot for many stocks almost everyday. Like viruses polluting intraday and eod data and deceiving computers and traders. Very annoying.

yet another loser

I believe China has the best solution to avoid this problem by stopping the trading for a stock for the rest of the day if the price is up/down 10% and also ban short selling.
