MT4's "Strategy Tester" is a multifunctional window where traders can test trading strategies (objective rules for trade entry, exit and management) with historical data.
Its ability to test and optimize a trading idea prior to placing it in a live market with real money is an invaluable step in the development of a profitable trading system. It will also help you train your brain.
There is no need to download historical data as it has the same in-built. It has a visual mode where you can replay all the market action bar by bar as if you are trading the live market. All this is free. You do not need to spend hundreds of rupees on buying costly trading softwares for this purpose.
I have made a small video demonstrating how to use “Strategy Tester” for market replay on Nifty 3-minute time frame chart. This is how I taught myself how to use Tester and set up the chart. If you know the better way to do, please share your method.
Go ahead and watch it and make the maximum use of it.
