150924 - v3.0 This script is a complete rewrite of the previous version here. It gathers market data from up to 8 different Bitcoin exchange pairs (8 is maximum due to script limitations).The influence of each single exchange can be customized individually, default is 50% for 0-fee exchanges, 10% for futures and 100% for all others. For each single exchange a standard deviation from the composite mean price and a average price range are determined. To make data from exchanges with different liquidity comparable, all single exchange price ranges are normalized to the range of the composite mean price. To make data from exchanges with different fee structure (= exchanges that constantly trade at a premium / discount) comparable, all single exchange prices are corrected by their respective standard deviations. To account for trade volume, all price data is weighted by the current candles volume. - optional Heikin Ashi candle display - optional EMAs - lots of switches to play around with ;-)
