Ive received a lot of recommendations about using various types of software for charting, technical analysis, backtesting, risk management, system dev, trading platforms etc. Ive never been faced with such a bewildering array of choices. In the financial software realm there seems to be a lack of clear distinctions between software categories (a lot of overlap). For example there are technical analysis packages that can be used to trade directly, like Tradestation, then there are ones that do backtesting but need a plugin to handle position sizing and risk management.
Are there any websites that have unbiased reviews or articles to help make sense of all this?
