output text on strategy optimiser chart

[hyena]

Hi,

I have been playing around modifying strategies in the strategy optimiser code and I want to check when my code logic lets a trade ride instead of closing out I am really struggling to get it to work,

I have tried using DrawTextFixed() and DrawDiamond() (just in case text was the issue) and I get no (my) text on the chart and only a red diamond on the last bar

I'm using imported daily data

any one have any ideas where to go next

thx

ian

Not without seeing the errant code.

Thanks koganam - Ian could you share the code snippets you used? If you apply the same strategy on a chart - any other behavior seen then?

Thanks,

hi,

Sorry about this, i had googled around and was pretty certain the answer would have been a ninja restriction on putting text/symbols on to SA charts from within the strategy code :

heres a snippet of the simple code ive been using to try get the text/symbols show (didnt keep the various iterations of trying to get text to show) before putting itim my working strategies

-------------------------------------

/// This method is used to configure the strategy and is called once before any strategy method is called.
/// </summary>
protected override void Initialize()
{
CalculateOnBarClose = false;
}
/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
if (CurrentBar < 1) return;
if ((High[0]-Low[0]) >1)
{
DrawDiamond("tag1", true, 0, Low[0] - TickSize, Color.Red);
}

Provided that your conditions are met that will draw EXACTLY one diamond on your chart, at the last position that met the conditions.

That is because you are using a fixed tag, so every time that the diamond is drawn, it is drawing the same exact object, just at a different place.

If you want to see all drawn objects, you need unique tags. The commonest method used in these parts is to concatenate the CurrentBar into the tag thus: "tagPrefix" + CurrentBar.To String(), as the CurrentBar is guaranteed to be uniquely mapped 1 to 1 to the chart bars.

Hi guys,

many thx .. had a bash and worked perfectly, for others benefit here are the lines i used to test it works with text and symbols (diamonds in this case) :

n.b. the "-L-" is the text i had it print on top of particular bars that met the condition in the IF statement and the "L-ROLLOVER" is the tag name which can be anything


DrawText("L_ROLLOVER"+ CurrentBar, "-L-", 0, High[0]+2, Color.Red);

DrawDiamond("L_ROLLOVER"+ CurrentBar, true, 0, Low[0]-2, Color.Red);

b.r.
