Not an issue, its pairs you limit, not trades.
Use MaxBuyTrades and MaxSellTrades to adjust max trades.
Started a small account myself to try the shotgun strategy, running at 1/2 the risk taken here with doubble floating TP on 9 pairs. 1.6% in 14 hours at 1.52% drawdown. The entries are not too bad. Will see if it goes bust in a month.
