# MetaTrader 5 build 1870: adding symbols to Market Watch by ISIN

## Search for trading symbols by ISIN (International Securities Identification Number) has been added in the Market Watch window

26 June 2018

### Terminal

1. Search for trading symbols by ISIN (International Securities Identification Number) has been added in the Market Watch window. Now, you can add symbols using three methods: by name, description and ISIN.

2. Fixed user interface slowdown when changing a trading account password.
3. Fixed occasional CPU load increase caused by the client terminal.

### MQL5

1. Fixed passing of custom HTTP headers in the [WebRequest](https://www.mql5.com/en/docs/network/webrequest) function.
2. Fixed behavior of the [Bars](https://www.mql5.com/en/docs/series/bars) function in cases when the range beginning and end dates are the same. Now, if there is a bar, the function returns 1. In earlier versions, the function unconditionally returned 0.

### Tester

1. Fixed start of single [testing in the visual mode](https://www.metatrader5.com/en/terminal/help/algotrading/visualization) after a [forward optimization](https://www.metatrader5.com/en/terminal/help/algotrading/strategy_optimization#forward).
2. Fixed sorting of optimization results. Now sorting takes into account passes with incorrect input parameters (INIT_INCORRECT_PARAMETERS) and those having no profit factor.
3. Fixed recalculation of genetic optimization graph after changing the optimization criterion.

Documentation has been updated.
