SSChart has a built in symbol TEST which generates data whenever a polled quote source is selected (such as yahoo). This symbol closely mimics the price action of the S&P500 e-mini futures contract (ES). It can be plotted in charts and paper traded using the Paper Trading window. The data is generated at normal speed when the quote polling interval is set to 5000 milliseconds under {File | Preferences}. It may be accelerated up to 50 times normal speed by setting the polling interval as fast as 100 milliseconds. If you accelerate the interval it is recommended you not be collecting data for any other symbols at the time. (I.e. the only charts open are for TEST, and no other SLFmaps, etc.). Make sure you reset the quote polling interval back to 5000 or another reasonable number when you are done using the TEST symbol since otherwise there will be excessive flicker in some of the charts due to constant redrawing. The trade rate for TEST is accelerated outside the regular session hours so the total trade volume ratio between regular session and extended session approximates the real trading pattern. When you first start generating data for TEST it starts at the current data/time and goes forward. If you generate it at and accelerated rate, the dates will reach into the future. When you restart, it picks up from the data/time where it left off. If you delete the TEST.* data files in the data directory, then the state will reset to start again from the current data/time. The data is generated using pseudo-random numbers and looks very realistic. You can use real random numbers by downloading a binary data file from http://www.random.org/files/ A one megabyte file will be more than enough. Save it in the SSChart DATA directory and rename it random.data1. When ever this file is present it will be used instead of the random number generator. The realistic appearance of the charts produced this way should tell you something about the real nature of the markets. |
