Hi Alessandro,
Please note that according to WealthSignals policies, a system can
not accept subscribers unless its author has uploaded backtest results using Wealth-Lab Developer v6.8 or higher.
Even if author posting fee has been paid.
Additionally, it's problematic to attract paying subscribers without the backtest results.
Please choose "Reset system data" from the Admin dropdown list, and then use the WealthSignals Publisher tool to upload its backtest history:
