Mql5官网 Tools Standard 外汇EA

Tools Standard is a color multicurrency/multi-symbol indicator. It is designed for displaying one of the seven standard indicators on candlestick chart in a separate window under the base symbol chart.

The indicator can be calculated based on one of the seven indicators according to user preferences:

0. Bill Williams Alligator
1. Bollinger Bands
2. Envelopes
3. Bill Williams Fractals
4. Moving Average
5. Two Moving Averages
6. Parabolic SAR.

Bill Williams Alligator is used by default.

The indicator may be used with any broker, irrespective of the name of the financial instrument since it is necessary to manually enter the name as an input parameter. If you enter a non-existent or incorrect name of a financial instrument, you will receive an error message that this financial instrument is unknown (does not exist).

Users also can set the number of displayed candlesticks, as well as select bullish and bearish colors including the colors of the applied indicator’s lines.

Limitations

A chart with similar parameters on the same symbol can be displayed only once. Otherwise, an error related to its re-using occurs. An appropriate error message is displayed and an offer to replace a symbol is made. However, this error message should be ignored when only parameters of the calculation indicator (already created in the window) are modified (see screenshots).

Recommendations

It is recommended to use the indicator with Bars_Number parameter not exceeding the number of bars fitting in one full window (about 250 bars).

Note

In case connection with a trade server is lost, the chart is re-drawn from the beginning using the number of bars set by Bars_Number and Bars_Flag parameters after connection is restored and swapping of data is under way.
