There is no automatic mechanism for re-importing exported expert advisors back in FSB Pro. However, your expert contains all the necessary information for recreating the source strategy.
Let's use the following strategy for example:
There are two places from where we gather information for recovering the strategy:
1. The expert advisor input panel. It contains all numeric values of the Strategy Properties and the indicators.
For example we see here that we have "Amount to add in addition: 0.01 lot", but we don't see what is the adding type (add, winner, nothing ...)
2. The expert advisor source code.
When you open the Expert Advisor code in the MT4 editor, you can search the phrase "new Strategy". It will bring you to the place in the EA where is the actual code for creating the strategy representation. It contains all details for the strategy except the numeric values. The numeric values are replaced with variables in order to be possible to reveal them in the Input panel.
The above screenshot shows new Strategy (1, 1) - it means the strategy has 1 opening logic condition and 1 closing logic condition.
The red arrows shows the type of same and opposite direction signals - Add and Nothing in that case.
Martingale, SL, TP, BE are enabled when the values of the expert input are not 0. This allows the traders to switch on and off these protections by only changing the numbers in the Input. When a number is 0, the option is off. You may use the information to recreate the strategy.
The code for creating indicators is below.
The green rectangle contains the info for the indicator name and the Advanced Indicator Properties. The code correspond to the indicator options. I market the numeric values of the indicators with green arrows. You see that we have variables instead of values. We take the actual values from the Input panel.
Try to recreate your strategies. If you have problems with some of the parameters, please post the EA and we will help you.
I'm planning to add a possibility to re-import the experts back in FSB Pro. It will works as in EA Studio.
