How does an EA really access indicator data ?

2 replies

7 years ago #115413

I have a custom indicator that I am trying to utilise in EAWizard.

When the indicator is added to a chart it starts to collect live ticks and apply various calculations to them. If the indicator is removed from the chart the accrued data is obviously lost.

My question relates to the ability to access the data from this indicator live within an EA. Can the EA keep an indicator running so that the data can be accessed or does it continuously open/close the indicator ?

I would be interested to know if there is a better way to utilise such an indicator, maybe incorporate the code within the EA rather than using custom indicator import ?

Any help / insights would be much appreciated.

Do you have the source of the indicator (MQ4) or just the EX4?

Because, the only way to access data from an indicator is through the indicator buffers. Internally collected ticks in an indicator would be internal to the indicator. When an EA uses an indicator, it is not unloaded unless the parameters passed to the indicator change, from one call to the other.

Yes I do have the source.

Many thanks for:- “When an EA uses an indicator, it is not unloaded unless the parameters passed to the indicator change, from one call to the other”. I searched the web for that information but couldn’t find it. Knowing the indicator is loaded means that it can work. I’ll keep at it. Thanks again.

Hypothetical Performance Disclosure:
Hypothetical performance results have many inherent limitations, some of which are described below. no representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
