Hello dear programmers, I'm having a problem with: possible loss of data due to type conversion from 'long' to 'double' {image} // Fill arrays with price and volume data for(int i = 0; i < bars; i++) { MqlRates rates[]; if(CopyRates(_Symbol, PERIOD_M1, i, 1, rates) > 0) { priceArray[i] = (rates[0].high + rates[0].low + rates[0].close) / 3.0; // Typical price volumeArray[i] = rates[0].tick_volume; } } Can someone help me with this? My sincere thanks in advance! "Edited:" This code is for mq5
That's not an error, and the code will work with this warning.
The variable array tick_volume[] is long:

And your volumeArray[] is double.

That's why you are getting this warning.
Define your volumeArray[] as long.

Google's AI Studio made quick work of fixing this up.
Key changes for continuity:

  1. Slope Calculation: The Slope[i] is determined by comparing current_T3_value with prev_T3_value. If they are equal (flat MA), the Slope[i] inherits the slope from the previous bar (Slope[i+1]).
  2. Assigning Buffers:

    1. Based on Slope[i], the current_T3_value is assigned to either MapBufferGreen[i] or MapBufferRed[i].


  3. Continuity Fix Block:

    1. This is the crucial part: if (i < rates_total - 1) checks if there's a previous bar.
    2. if (Slope[i] != Slope[i+1] && Slope[i+1] != 0) checks if the slope direction has actually changed from a decisive state (not 0).
    3. If it changed, the buffer corresponding to the previous bar's color (Slope[i+1]) is also assigned current_T3_value at bar i. This makes, for example, the green line draw up to the point of change, and the red line starts from that same point.


Other notable changes/improvements:

  1. Changed init() to OnInit() and deinit() to OnDeinit() for modern MQL4 syntax.
  2. Used Digits() instead of MarketInfo(Symbol(), MODE_DIGITS).
  3. Adjusted SetIndexDrawBegin to be more dynamic based on MA_Period.
  4. Improved logic for start_bar_loop_idx in OnCalculate for initial calculation and updates.
  5. Added more robust seeding for eN arrays, especially for the prev_calculated == 0 case, to handle the eN[(rates_total - i) - 1] access correctly.
  6. The eN array indexing rates_total - i means eN[1] corresponds to the oldest bar i = rates_total - 1, and eN[rates_total] corresponds to the current bar i = 0. eN[0] is used as the "previous value" for calculating eN[1].
  7. Matched #property indicator_widthX to SetIndexStyle width.

Test this version. The line should now be continuous at color change points. The logic for eN array seeding and indexing in T3 indicators can be tricky, so minor adjustments might still be needed depending on edge cases, but the core continuity fix should work.

So, you need to do the same for every case.
If you don't want any warnings like those, you need to be consistent and use the correct variable type.
Because you are still using type double and reading type long.
Thus the warnings.

Hie everyone, i am using this indicator: DaVinci Telegram OpenClose Indicator v.1.9.mq4, in my private Telegram channel to give signals to a few colleagues, it only posts messages as text, so i wanted to use the visuals of emojis so that it makes a difference for: Buy & Sell Orders opening, then Buy & Sell Orders Closing with Profit or Loss. the snippet for what i am saying for instance: // Correct UTF-16 surrogate pairs for emojis vertical_robot_emoji = CharToString(0xD83D) + CharToString(0xDEA6); // U+1F6A6 green_circle_emoji...

Hi

use the U+1F6A6 code and replace U+1 with \x

vertical_robot_emoji = "\xF6A6"; // "[ROBOT]";

I didn't say, I just copied from your post and pasted it to say it was "mq5'. I want to thank you for your energy on this magic, very agile... I have two of these codes to adjust: if you want to check, I can share them here, I also developed them using AI, it looks interesting, but I also couldn't fix the errors in mq4 and mq5. If you want, I can send them here to check if you have some time.

I checked the codes on mql5.com, most of them use iCustom, not iMA, iMACD, etc.
Don't think there is any difference in outcome.

result of my test shows something different. Using the code below, I retrieved data from the one-hour timeframe and passed it to a custom function
That's probably because the mtf price history has already been loaded, and so everything else would also work, ie it won't work if the mtf data hasn't been made since the terminal turned on, on loading copyrates would return -1.

I'm curious how the attached file works on your end-

In all the tests, I changed the time frame to 5 minutes, then closed and reopened MetaTrader to test the indicators.
All images are animated.

Test 1: The indicator I have currently built for multi-time frame using 1-hour candle data.

Your indicator manages the time range where the higher time frame data needs to be copied very well; it even works better than my indicator, which is still in its initial version. The version I built uses artificial intelligence and does not take into account the time range needed for copying the higher time frame data.
For now, I can conclude that at least one solution exists for when we are offline.

{quote} I read this, and I think that this should clear up a few things for you: https://www.mql5.com/en/forum/1906 You can't expect a code to work offline if the data file isn't filled with data and then these data aren't copied to buffer, because the data aren't in the file, or the file doesn't exist.
Thank you very much for the time you spent.
I checked the link you posted here along with the links inside that page at least three times. I even gave the links to an AI for research and asked many questions.
The issue is that the answers from those people are for normal conditions.
At least, people always assume normal conditions when answering and think that the person asking is not aware of the basic points.
I’m not judging, because I usually have the same perspective in my own answers.

Now, here is what I think:
I understand what a handle is - it’s like an ID that only needs to be created once. Just as we don’t set the indicator’s name on every market tick, we don’t set an ID on every tick either.
Also, that handle has no use and no calculation is done until we use the copy buffer.
So far, there is no problem, but I have an issue with the data.
Does candle index 0 in the 1-hour timeframe match as the multi-timeframe reference time with other timeframes? Yes, it does in my chart.
If we identify the first swing high or low in the 1-hour timeframe and then move to a lower timeframe, do we have data at that time and price? Yes, a quick look shows that we have data in the same time and price range on other timeframes.
When I see the 1-hour timeframe data with my own eyes and it matches the lower timeframe, but the multi-timeframe indicator doesn’t work, it doesn’t mean we don’t have data.
Either I don’t know how to code the indicator to read data from the hard disk, or MetaTrader doesn’t have such a capability.
In the end, there are only two possibilities:

  1. I am making a mistake in coding
  2. The problem is with MetaTrader itself.

This indicator was programmed by Mr. Jeanlouie (for which I am truly grateful), but it has two minor issues: one is that when you put it on the graph, it freezes for a few minutes, just like when you change the Tf, and two is that sometimes you have to refresh it to see if the arrow has appeared. Please, if you could fix this, I would be very grateful.
