You've tested a range of settings, sorted the results and found a clear winner. I would save that result. I would also save the settings around it.
The top row tells you which configuration scored highest in the search you ran. To decide whether it deserves more attention, I want to understand how that result fits into the rest of the search.
If changing an input slightly produces very different behavior, the winning configuration may require a more careful explanation. The same applies when the result depends heavily on one short period or a small number of trades.
Decide what you are optimizing
Profit, drawdown and trade count answer different questions. Before running a search, write down the purpose of the test and the conditions under which a candidate would be considered further.
For example, you might require enough observations to inspect losing periods and a drawdown profile compatible with your research objective. The exact requirements need to suit the strategy; copying a universal threshold can create a false sense of precision.
Save the parameter ranges and selection criterion as well as the winning row. Without the search context, someone reviewing the result cannot see how many opportunities there were to find an attractive historical configuration.
Look around the winning settings
A neighborhood of reasonably consistent outcomes is a useful subject for further investigation. It doesn't establish a future edge, and some parameters legitimately change behavior at specific boundaries. The point is to understand the pattern rather than assume every small change should produce the same result.
Try to explain why the selected settings make sense for the strategy. If the only explanation is that they produced the highest return, you still have a research question to resolve.
Reserve an evaluation period
Keep data aside that you don't use to choose or revise the settings. Apply the selected configuration there under documented conditions.
MT5 supports a historical forward-testing split as part of optimization. That is still a simulation on historical data; it is distinct from running a frozen configuration prospectively as new observations arrive. The optimization guide describes the available search methods, and the testing guide explains test setup.
If you inspect the reserved period, change the settings and try again, that period has influenced development. Keep that history visible and use a new evaluation for a new claim of independence.
I would finish this process with the chosen preset, the reason for selecting it, the alternatives examined and the remaining evidence gaps. The best historical row can start a useful investigation. I want the selection process to be visible before it becomes a recommendation.
Educational discussion. No optimization or independent evaluation was performed for this article. Historical results do not guarantee future performance.
