Has anyone already answered the question of how to do backtesting? backtesting is a must! A trading strategy doesn't last forever. You have to constantly adapt it to the market. New traders come, old ones go -> new strategies come, old ones go. The market and its processes and reactions change daily. I do automated backtesting with a small program I wrote myself in Python. It automatically checks at night with the data from the previous day to see if everything is still OK. I also have some other strategies tested and certain small deviations in all of them. In the morning the result is always ready when I start the day. Then it's up to me which strategy I choose today. A little human touch is always good, e.g. like yeserday when FED decisions are on the way, the market may behave differently than usual. I get the backtest data (Futures Level2 Tick) automatically as CSV file via daily download from BackTest Data If you are interested in discussing the python program, or my strategy, feel free to contact me
You will find out what you need as you go along. Companies like Ninja Trader or Trading View make your trading easier at a price. The price is a fee and to know what you are doing. They ask for a fee because people think that when they pay for something, that service is good. If it is free they start asking questions. People are suspicious when a service is free. So those companies charge and know what you are doing. They obviously sell your strategies to others if they are good. Those "others" are completely out of your reach. If you develop your own indicators and strategies locally with a programming language, only your broker will know what you are doing. They also sell your data to others. The same others. Just start doing whatever you want to do, and you will end up using the tools that you need.
