Not all strategies makes money all the time. You still need to keep an eye on it!
Mostly they do make money yes. They make as much money as you willing to put effort in to.
As mentioned before run it on demo account for at least a month.
Export the results from backtesting to a spreadsheet and note which days have most losses and or between which hours.
Depending on the strategy the DAX might lose money on Thursdays and FTSE on Fridays or EUR/USD on Tuesdays. On another strategy you might need to disable trading between 20:00 and 9:00. Another strategy might run well day and night 5 days a week. These mentioned are just examples what to look out for (not stating as fact the DAX has poor performance on Thursdays etc).
Good practise is to export the results from the strategy you run on Demo every week and analyse when what happened in the market. Note the market pattern VS your strategy. The market leaves clues.
Run backtest and WFA again every 2 weeks or so even if you have it live.
Autotrading is not the “holy grail”. It’s not case of write code once and let it run and you go sit on the beach and come back rich. No. It still takes work and dedication. The market might still turn against your strategy and you might lose money 12 trades in a row.
As with manual trading you have to hedge yourself. Have multiple strategies that “covers” each other if the market moves against you on one strategy.
There are many factors to take in to consideration hence the word STRATEGY.
