strategies interdependencies

[tonynt]

Hello,

I want to ask please if there are interdependencies that might cause issues when running 2 scripts on same instrument, eg one script in a range chart and another script in a tickchart. Both scripts in onbarupdate there is the check if flat or long or short. Can there be some issue with stops or with conditions because of the other script maybe?

I use different ordernames:
entryOrderSr1a=EnterShort(4,1, "rS1a"); // strategy running in a range-chart
entryOrderTSr1a=EnterShort(4,1, "TrS1a"); // strategy running in a tick-chart

It seems there is an issue with my lines I´m working with (for catching pivots, moving stops...) that I remote with my customized buttons. When I moved the line in one chart it doesnt work in the other chart anymore. I have in onbarupdate
if(shortlinedraw==false)
{
if(storeshort>0 && (Closes[4][0]>Lows[4][0]-1*TickSize || Closes[4][0]<Highs[4][0]+1*TickSize) && shortlinedraw==false)
{TxShortLine = Draw.HorizontalLine(this, "TxShortLine", true, Highs[4][0]+2*TickSize, Brushes.DeepPink, DashStyleHelper.Dash,2);shortlinedraw=true;TxShort Line.IsLocked=false;}
}
if(shortlinedraw==true)
{
if (DrawObjects["TxShortLine"] != null && DrawObjects["TxShortLine"] is DrawingTools.HorizontalLine)
{
shortlinePrice = Instrument.MasterInstrument.RoundToTickSize(TxShor tLine.StartAnchor.Price);
shortlinevalue = shortlinePrice;
}}

I could build this from the helpguide. Do I have to add something so that when I move the line it does not have impact on the line in the other script?


Thank you!

Hello tonynt,

Strategies do not know what other strategies are doing so they can submit conflicting actions and become out of sync. If you need to run two strategies on the same instrument it is suggested to combine the logic into one strategy and just run that.

Regarding your lines I couldn't say what may be happening there, have you tried to debug the code using prints? A script can only manage its own lines so if you are drawing from two scripts you would need to make sure to use unique tag names for each scripts lines.
