Hello f.saeidi,

Thank you for your post.

Your condition is checking if the RSI is greater than 70. As long as that condition is true, each call of OnBarUpdate() will result in the logic within the condition being executed. The Arrow will continue to be updated as long as the RSI is greater than 70. Are you saying that you want the arrow to only be drawn once when the RSI reaches a value greater than 70? In that case, you may need to change your condition to check when RSI crosses above 70 with CrossAbove():

now i can get buy signal and arrow.
but problem is when for first time rsi > 70 i can get arrow
but for second time when rsi >70 previous arrow was clear and shift to right side.

[f.saeidi]

in fact for example when 4 times rsi > 70 i must see 4 time buy arrow
but i can see only 1 arrow and shift to right side.

Hello f.saeidi,

Thank you for your reply.

You are currently drawing the arrow with one tag called "tag1"
Draw.ArrowUp(this, "tag1", true, 0, Low[0] - 4*TickSize, Brushes.Green);

If you'd like multiple arrows to be drawn, you need to use a unique tag for each one. Otherwise, when using the same tag, the same object is simply updated/modified. You could append the CurrentBar index to create unique arrows:
Draw.ArrowUp(this, "tag1" + CurrentBar.ToString(), true, 0, Low[0] - 4*TickSize, Brushes.Green);

The Tag is described here as "A user defined unique id used to reference the draw object.

For example, if you pass in a value of "myTag", each time this tag is used, the same draw object is modified. If unique tags are used each time, a new draw object will be created each time."

Thnx for your notes.
Can I add one window?
For example when buy arrow active one window open and write instrument name with buy condition.

Thnx for your notes.

For example when buy arrow active one window open and write instrument name with buy condition.

To create a window that will open via NinjaScript, that would require you to script an AddOn window and initiate that AddOn window from your script when the desired conditions are met. This has been discussed in the thread here:
