1. A method of displaying a performance indicator symbol upon a price chart, the method comprising:
using a computer device comprising a processor, a memory, and a network access interface, where the memory stores a charting engine;
receiving by the network access interface, from a first data source having a first use, user account transaction data of a trade of a quantity of units of a market-traded object transacted at a first time at an average cost per unit, the trade indicative of opening a trading position in the market-traded object;
receiving by the network access interface, from a second data source having a second use different from the first use of the first data source, market data including a last price of the market-traded object that occurred at a second time, wherein the second time occurred after the first time;
determining by communicating with the processor, an average price from the last price and the average cost per unit;
determining by communicating with the processor, whether the last price is greater than the average price;
determining by communicating with the processor, whether the opened trading position is a buy-long trading position or a sell-short trading position;
in response to determining that the opened trading position is a buy-long trading position and determining that the last price is greater than the average price or in response to determining that the opened trading position is a sell-short trading position and determining that the last price is not greater than the average price, generating and displaying using the processor in operative communication with the charting engine, the performance indicator symbol at a particular position, by drawing upon the price chart of the market-traded object, a first vertical line from the last price at the second time to the average price at the second time indicating that the opened trading position in the market-traded object is outperforming the average price; and
in response to determining that the opened trading position is a buy-long trading position and determining that the last price is not greater than the average price or in response to determining that the opened trading position is a sell-short trading position and determining that the last price is greater than the average price, generating and displaying using the processor in operative communication with the charting engine, the performance indicator symbol at a particular position, by drawing upon the price chart of the market-traded object, a second vertical line from the last price at the second time to the average price at the second time indicating that the opened trading position in the market-traded object is underperforming the average price.
