Yesterday, MetaQuotes has released a new update for the MetaTrader 5 platform - Build 1455. Today, it has become available on some brokers' servers. The new version focuses on adding some handy libraries to MQL5 standard library collection, making the developers' work much easier: Order opening dialog window now features tooltips for Buy and Sell buttons to explain to traders what is going to happen when the buttons are clicked. Not very useful to experienced traders, the tooltip will reduce errors among newbie traders. Added new icons for deals, orders, and positions in Trading and History tabs of the terminal. Now it is easier to tell ones from the others and shorts from longs. Optimized update speed for Depth of Market and tick charts. Optimized synchronization of ticks data during off-market hours. Added ALGLIB library to MQL5. Added Statistics library (similar to the R language) to MQL5. Added Fuzzy library to MQL5. Added CHART_QUICK_NAVIGATION property to enable and disable quick navigation bar on a given chart via MQL5. Added FileSave() and FileLoad() functions to quickly save and load numeric arrays to a file specified using a string name instead of a file handle. Unfortunately, the documentation has not been updated to include help files for these new functions. It is now possible to set different colors for drawing the candles in custom indicators using DRAW_CANDLE style. There are three modes: one color for all candles, two colors for candle edges and candle bodies, three colors for edges and bullish/bearish bodies. Fixed bugs with CopyTicks() function. Operators can now be used in interfaces in MQL5. Strategy Tester interface is now available in Greek, Malay, and Hebrew.
