Improving my EA + Bugfix

The source code is ready to provide. But it will be only provided for the developer which wins the application. The project is very simple:
- Add a bugfix
- Make a new input and add this in the trading logic

Trading Logic
The trading logic is very simple. Open a limit order on the first imbalance which got created after 17pm and before 18pm (NY time --> UTC-4). But now I want to have a new possibility WHEN the EA opens the limit order. Right now the limit order gets opened at the beginning of the imbalance.

Make a new input
Enter at % of Imbalance: 0% / 25% / 50% / 75% / 100%

—> The user should have the availability to choose between entering at the beginning of the Imbalance (current code which will be 0%), entering at 25%, 50%, 75% or at the end of the imbalance which will be 100%. According to this setting the EA should calculate the correct lotsize depending on the stoploss and the tisk input.


Bugfixing
There must be a bug in the lotsize calculation if I choose a different asset than indices. If I run the EA at for example GBPUSD then the EA always wants to open 500 lots and ignores the risk input. The EA should run on all assets an calculate the correct lot sizing. Please improve and backtest.
