Hey guys, I felt like there may be a need for a chart markup indicator for EasyLanguage.

So, here is what I came up with so far tonight. It will mark the Open, High, Low, Close, and the gap. It works best on a RTH chart (vs a Globex chart).

Each trendline color is configurable.

Let me know what you think, and feel free to make enhancements and share them back

One known problem is the lines/text are drawn per the GetAppInfo(aiLowestDispValue) meaning they will align themselves to the bottom of your chart just above the time axis. This works great in "real-time" if you load the indicator or reload it, but as you scroll back or forward, these past plots do not re-calculate or re-align themselves. I am not sure how to fix this, I am open to suggestions! It means that you may need to reload the indicator/refresh it to see the plots on historical data.

Another known limitation is it works only on 1 minute or 5 minute charts (well, I guess 30 minute could work too actually). This is due to the time recognition I coded for the open/close times. There has got to be a better way to do this, let me know!

Here is the EasyLanguage code:

Mike - thank you so much for putting this indicator together, I'm having a problem with the Gap when using on the ES .... it doesn't show the correct number and I'm not familiar with your contruction:

if O > lastclose then txid_gap = Text_New(date, time, lastclose - textoffset, text("Gap +", ((O-lastclose) / MinMove*PriceScale):0:0));
if O < lastclose then txid_gap = Text_New(date, time, lastclose + textoffset, text("Gap -", ((lastclose-O) / MinMove*PriceScale):0:0));

Can you please point me in the right direction? Thanks in advance.

Are you using a RTH chart or a 24h chart? I think the error might be in the Open price, which is used for the gap.

On the menu, did you enter the open and close time precisely in the format of "H:MM:SS AM" ? So for 9:30am on ES you need 9:30:00 AM. You might try changing it to 9:35:00 AM and see if that does it, since your first candle might be the Open candle, otherwise it would need code changes.

Mike

Mike - please see attached ... it shows the Close, Open and also the Gap but the gap amount is incorrect (should not be 24).. looking at the code it seems the calculation is correct, just the display is incorrect..

Gotcha, I see. It has to do with the Tick Size (MinMove/PriceScale) most likely. I only tested it on CL, and ES is different.

I'll take a look at it as soon as I can.

I tested this on my side today for the ES, it seemed to work fine (no code changes).

I am central time.

I set the "open" to "8:35:00 AM", because the time stamp of the bar is the closing time of the bar in MultiCharts. I set the "close" to "1:30:00 PM".

I believe it worked correctly. The gap is listed as +3, as in 3 ticks. The open is @ 1213.50 and the close 1207.50. The high is 1216.50 and low 1207.50. The close-to-close was -21 ticks from yesterday.

Shown here:

I had incorrectly been using 8:30:00 AM it should be 8:35:00 AM, please take note (For ES, central time). For CL it would be 8:05:00 AM (central time).
