Today I'm going to try your way, let's see if it literally already generates with the not coming out

Follow the steps and 100% of strats generated will have exit indicator as "Do not exit" and hence useful for SL and TP.
1] Open file:- bin/lib/xgen.min.js

2] Find in the file:- t.openOnlyNames=["Entry Time","Long or Short","Pin Bar"]

3] Replace it with:- t.openOnlyNames = ["Accelerator Oscillator", "Accumulation Distribution", "ADX", "Alligator", "Average True Range", "Awesome Oscillator", "Bears Power", "Bollinger Bands", "Bulls Power", "Candle Color", "Commodity Channel Index", "DeMarker", "Directional Indicators", "Donchian Channel", "Entry Time", "Envelopes", "Force Index", "Long or Short", "MACD", "MACD Signal", "Momentum", "Money Flow Index", "Moving Average", "Moving Average of Oscillator", "Moving Averages Crossover", "On Balance Volume", "Pin Bar", "RSI", "RVI", "RVI Signal", "Standard Deviation", "Stochastic", "Stochastic Signal", "Volumes", "Williams' Percent Range"]

4] Save and don't forget to use --max_exit_slots 1 --ind_exit_time false

5] Enjoy !

return collectionRecords.map((rec) => {
    // ... other code ...
    strategy: {
        properties: {
            // ... properties ...
        },
        openFilters: rec.strategy.entryParams.map(mapIndParam),
        closeFilters: rec.strategy.exitParams.map(mapIndParam),
        timeUpdated: rec.strategy.timeUpdated,
    },
    // ... other code ...
});

Modify the closeFilters part to always use the "Do not Exit" indicator. Replace the line:

closeFilters: rec.strategy.exitParams.map(mapIndParam),

subscrube foir

closeFilters: [{
    name: 'Do not Exit',
    listIndexes: [0],
    numValues: []
}],

5. Save the file after making these changes.
These modifications will ensure that all strategies are saved with the "Do not Exit" indicator as the only exit indicator, regardless of how they were originally generated.
Note: This change only affects how strategies are saved, not how they're generated or tested. For the generator to use only "Do not Exit" during generation and testing, additional changes to other files would be necessary, which only Popov can implement.
After making these changes, all your strategies will be generated with no exit. You should then perform a single test again using the Express Generator as a validator, or even optimize it, because by default, the "Do not Exit" will always be included, and it won't close positions prematurely before reaching TP or Stop Loss.
Another observation: in your .ini configuration file, it's necessary to set only one slot for closing operations as the default.
I sincerely hope this tutorial has made you as happy as it has made me. While it's not the ideal solution we'd prefer, consider this: if you generated 1 million strategies using Express and they were saved with these modifications, after performing a single test, you'd be left with 700,000 strategies. That's only a 30% reduction, which is truly remarkable as it doesn't make such a significant difference.
Trade safely, everyone!
