MaxListenersExceededWarning when running bruteforce

Hi,

When running bruteforce, I receive this message during the console output:

Complete: RSI_BULL_BEAR USDT/BTC 5/1000 Binance
Started: RSI_BULL_BEAR USDT/BTC 5/1000 Binance
(node:22519) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 201 unhandledRejection listeners added. Use emitter.setMaxListeners() to increase limit

The bruteforce backtest does seem to continue to run properly.

Batcher's config.js:
