摘要： A trading system enables investors to execute trades electronically on exchange at prices that are chosen in consideration of the derivative nature of ETFs as a portfolio of securities or other financial instruments. In addition to measuring liquidity in the ETF itself on exchange, the trading system analyzes the liquidity of the ETF's underlying portfolio to understand the liquidity that is available to investors in the ETF through the creation/redemption process. By monitoring the bid/ask spread of both the ETF and the underlying portfolio in real time, the trading system enables investors to leverage the full potential liquidity of ETFs. The trading system can be used to manage the data and pricing infrastructure for identifying these liquidity replenishment points and to make these prices actionable for investors.

摘要翻译： 交易系统使投资者以交易所的价格以电子方式进行交易，这些价格是以考虑到ETF衍生性质作为证券或其他金融工具投资组合所选择的。 除ETF本身交易流动性外，交易系统还分析了ETF基础投资组合的流动性，通过创建/赎回流程了解ETF投资者可用的流动性。 通过实时监控ETF和基本投资组合的买卖价差，交易系统使投资者充分利用ETF的全部潜在流动性。 交易系统可用于管理数据和定价基础设施，以识别这些流动性补充点，并使这些价格对投资者有效。

摘要： A cathode ray tube deflection system which consists of a series of weighted current steps utilizing switches to drive a deflection coil directionally sweeping over a screen. A transistor isolates the deflection coil from the switches. When a switch activates or closes, the transistor saturates and the current through the deflection coil rises linearly. The current through the deflection coil is limited to that determined by the current summation through resistor circuits connected to the switches or input terminals. The amount of current passage through the deflector coil determines the amount of movement over the screen.
