This unit test frameworks eases the development of unit tests for more complex expert advisor programs. The MQL5 developer can test single components. The test framework starts the strategy tester so that there is test data available if required. I am using the framework to do test driven development (TDD) on my MQL5 programs.

The 8 effective steps to build a robust day trading plan using Fibonacci retracement

Copy trading has become such a critical feature of forex trading. Some people see this as a potential business opportunity, while for opensource die-hards like me, we believe in giving back to the community rather than putting a price tag on everything 'nice'. So here it comes. A free opensource trade copier, which you are freely allowed to modify and distribute according to MIT license terms. It still has limited features, but the essentials like lot normalization are there. Please note that this copier only works for trading terminals installed on the same machine. Please share back any upgrades, enhancements or bug fixes to the discussion. Enjoy!

The Stochastic RSI indicator (Stoch RSI) is essentially an indicator of an indicator. It is used in technical analysis to provide a stochastic calculation to the RSI indicator. This means that it is a measure of RSI relative to its own high/low range over a user defined period of time. The Stochastic RSI is an oscillator that calculates a value between 0 and 1 which is then plotted as a line. This indicator is primarily used for identifying overbought and oversold conditions.
