Spot trading means you’re not technically “buying” the cryptocurrency, but instead trading your USD for it through either a market or a limit order. A market order means you agree to trade for the currency at the current market price. A limit order lets you put in a designated price at which you want the trade to occur, and when the currency reaches that price, the trade happens automatically. These orders then incur “maker” (for limit orders) or “taker” (for market orders) fees — though on Binance.US, there’s just a standard 0.1% fee.
The horizontal axis shows the time; relationships positioned towards the leftmost area of a diagram occurred at the start of the data interval considered, and those at the rightmost end occurred at the end of the data interval considered. The vertical axis shows the period; lower period bands (higher frequencies) are shown near the top and higher bands (lower frequencies) are near the bottom. Lower bands would be of interest to investors with short term horizons, whereas higher bands would be of interest to investors with longer term horizons.
