Get values for specific number os bars
Hint:
iHighest() is used to find the bar index among a range of bars
iHigh() takes that index and finds tthe high price
Hi phy,
Thank you.
I have found on code library this two functions. My problem is that I do not to construct an array routine to find those values.
Can you please post a sample code on how to do it? That way I will try to adapt it to my needs after I understand your sample code...
Thank you once again
Paulo
No special array needed, it reads from price history.
Hi phy,
What about if I need it to consider only from the first bar on the new open market? Imagine that I get a signal at 1AM GMT, if it counts the last 5 bars (on a 30M timeframe) it will also consider the last bars from the closed (yesterday) day trading...
I take this sample on the mql library but unfortunetly they do not tell me nothing... I am a newbie programming in mql.
- For iHighest:
double val;
// calculating the highest value on the 20 consequtive bars in the range
// from the 4th to the 23rd index inclusive on the current chart
val=High[iHighest(NULL,0,MODE_HIGH,20,4)];
When it refers to 20 consecutive bars in range, does it refers to 20 last bars? If so, is the actual bar included?
Besides being a newbie on mql programming, my mother language is Portuguese and as you may understand it is difficult for me to understand some of English expressions.
Thank you very much
Paulo
----Bars on chart or price history---------------------------------------------------------
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbcccc
val=High[iHighest(NULL,0,MODE_HIGH,20,4)];
iHighest() finds the index of the highest "b" bar ( among 20 bars) and High(iHighest()) finds the high price of that bar
starting with bar 4
the current bar is bar 0
Bars on chart:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbcccc
val=High[iHighest(NULL,0,MODE_HIGH,20,4)];
finds the index of the highest "b" bar ( among 20 bars) and finds the high price of that bar
starting with bar 4
the current bar is bar 0
Dear phy
Your help is very helpfull. Thank you, thank you very much.
I have made some tests and I learn another way to find the highest/lowest price from a specific number of bars.
I also now that if I need to know if some of this bars have reached/touhced a specific value I can do it by testing the final valur for the "val" variable, like:
if (val >=x)...
What about if I need to get and pass the highest value of each bar counted? Not just the highest value for a number of bars, but the high price for a specific number of bars? For instance aaaaaaaaaaaaaaaaaaaaabbbccc... pass the high value of 3 bars starting from the third passed bar?
Also if possible, just consider from the first bar from the open market. That is, TODAY and not considering the yesterday bars?
I am very sorry to ask you all this codes,
Thank you very much once again

Paulo

High[3]... High[4]... High[5]

iBarShift() takes a time value as input and returns a bar index to work with.Hi phy,
I will try with these new code provided.
I will let you know the results

Hi there,
Perhaps some of you can help me developing a specific code I need.
I know that the routines are already included on mql language but my problem is that I do not know how to program it.
I am using a 30M timeframe and I need to get the values for a specific number os bars. The values I need are, higher, lower, open and close for a specific number of bars.
The idea is to decide if enter a position or not based on support, resistances and pivot point.
I need to enter long when the price reaches resistance 1, but none of the last 5 bars have crossed/touched the pivot line. Or enter short when the price reaches support 1 and none of the last five bars crossed/touched the pivot point.
That is, if the last five bars did not touched/crossed the pivot line and are above resistance 1, I BUY. The inverse happens with sell.
I already have the code for the PIVOT, R1, R2, R3, S1, S2 and S3 just don't know how to calculate the value for the last x bars.
Also, and if possible, I need to get the value for the first bars on the market open. Lets say, the 5 first bars.
Thank you very much
Regards
Paulo
