Kline/candlestick close for every coin every minute?

Hi, before I try to code something myself, is there a simple way to get real-time closes for every coin? I know it's technically possible to use the API to get the closes for each coin individually but this would hammer the API and get me temporarily banned. I know I can get all_tickers in one go, but these don't contain the closing price for the previous candlestick, just the current price, which fluctuates wildly during the trade.

In simple terms I want to use TALIB to get the MACD data for every coin to help shortlist those that are potential buys. If there's an easier way than to hack this together myself I'd love to know!

Thanks
