how to get the close price of 1m period?

[etn1]

I need to know the closing price of a timeframe set to 1m. In particular, I need, for example, the values I circled in the image to be able to monitor maximums and minimums in a given period of time. 

I noticed that the values shown on the chart correspond only to the closing values of the candles. I tried to use the values of each tick using the function Symbol_last but as obvious that it is I got all the ticks thus reconstructing a graph that does not correspond to what I need.

please help me

2. On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

   On MT5: Unless the current chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.
