Candlesticks indicator

[sam30]

Hi,
I'd like to convert my indicator to plot with candlesticks (like ValueCharts). I get candlesticks but it's not correct. Explanations :

My indicator returns a value which is a double :
value += (bal - value) * multiplier;

Then I try to adapt to Roonius sample :
balance.Set(value);
balanceOpen.Set(balance[1]);
balanceClose.Set(balance[0]);
balanceHigh.Set(Math.Max(balance[0], balance[1]));
balanceLow.Set(Math.Min(balance[0], balance[1]));

2 issues :
- no gap as expected but I'm more concerned by the 2nd issue now
- no tails (highs, lows)

I tried working with value as a DataSerie but still the issues.

Thanks for your help

Hi sam30, thanks for your post - have you plotted the 'value' itself and checked for correct calculations? I would imagine if it doesn't change much from bar to bar you can get nonexisting highs / lows in the final plot.

[sam30]

Yes I can plot the 'value' itself and it changes a lot from bar to bar.
For example, I can see the candlestick going up then it goes a little bit down but the high is not plotted.

sam30,

Please print your balance[0] and balance[1] values to see what is happening.

Hi Josh,
I added this indicator to a 5 sec chart and do :
Print(DateTime.Now);
Print(balance[0]);
Print(balance[1]);
Print("\n");

So by 16:52:45 your balanceHigh plot should be -4,72418112484343. Please confirm/deny this.

[sam30]

Yes I got this high but the problem is there :

Now I print :
Print(DateTime.Now);
Print("Open : " + balance[1]);
Print("Close : " + balance[0]);
Print("High : " + Math.Max(balance[0], balance[1]));
Print("Low : " + Math.Min(balance[0], balance[1]));

And I get the expected result (but not what I want), see below.
For every new 'value', the high/low are calculated but I want to keep the high/low for the actual bar (here 5 sec).
So I guess I have to create other DataSeries to store the highs/lows...

sam30,

You should not be checking balance[0] against [1] in that case. You should be checking the incoming tick against the previous stored high value. Only store a new one if the new tick is higher than the old high.
