The FOREX calculator uses the Adaptive Channel lines to determine your initial stop. You can input your portfolio value, % risk per trade and it will determine the number of lots. It will automatically recalculate when you switch to a different currency pair. You can choose to go long or short the currency pair and the number of lots will recalculate. There is also an option to choose your own initial stop value. Helps you stay consistent with position sizing and risk management.
The Adaptive channels can also work as entry points and to follow the trend of the trade until it reverses. The calculator works on any time frame from 5 minute charts to weekly charts.
This version uses the U.S. dollar as its base currency when calculating pip value and position size. It also calculates on roughly 30+ pairs. It doesn't convert to other currencies yet, but the plan is to add other base currencies in the near future.
