Indicator only shows up for limited time

Hi there,

I am having an issue where the indicators i insert in metatrader chart only shows up for few months back from today. the charts are there for a year or more, but the indicator only shows for past couple of months. now this is random....sometimes it will show for 4 months, sometimes 2.....any help appreciated.

Thanks.

Hello
It is important to know how many bars are in history. To find out you go to TOOLS/OPTIONS/CHARTS and select the number of bars you want. if you are working with 4 hour bars with approx 30 bars you get a week. If you are working with 5 min bars then every day is 288 bars. So 28800 would give you a 3 month history of 5 min etc etc.

I am dealing with 1 hour charts..Max bars in charts I have set as max...250000. see the thing is I am trying to backtest some indicators....now one of them is as simple as EMA. the data goes back past 1 year or more, but the indicator shows up only for 2-3 months.

tHANKS a lot for your support brother. attached is my template. I understand your point about needed data points.

there is no problem with your template or indicator.
First make sure that you have the bars correct. (Tools/Options/Charts) and put a big number for both Max bars in history and maximum bars in chart.
Then what you think is a problem is your long ema (800). It is not always on the screen because it is either on the upper part of the chart or the lower part and it is hidden. So in order to be able to see it right click on your chart and select properties and then change the scale to fixed and put a number that will show you the indicator. For gbp/usd put 1,80 as the lower part. After you make sure your indicator works bring it back to normal. Anyway since you are working with Rob's setups when the 800 is not on the screen you do not need it.

actually look at the last gbp/usd tab.....there are the ATR Lines, red and blue. those lines only go back to two months even though data is there for last 2 years or so......

In the template sent there are no ATR lines. I added the ones included in metatrader and there is no problem on my platform. I suppose that ATR stands for Average True Range.

Ok sorry my mistake. here is the correct template : its ATR Lines for the strategy called Bat By Team Aphid. i AM ONLY getting the ATR Lines from feb to current. I have also included the indicator called BAT ATR V1. thats the one I use.

//---- indicator parameters
extern int BackPeriod = 1000;
extern int ATRPeriod = 3;
extern double Factor = 3;
extern bool TypicalPrice = false;

These are the first lines of the indicator. I see a Backperiod set to 1000. And as expected it did not go far. If you change this line in the indicator to let's say 10000 it will show you much more. Of course it is better to ask the creators of the indicator why they have this limitation. I understand that it will calculate faster. If this is the only concern of the creators then you can go and change it.
Regards

thank you very much that fixed it......
