Get direction of trade?

[cyanidez]

Hi guys!

Can you please help me? I have written my own strategy, where one of the parameters is as follows:

Code: Select all

strategy.parameters:addString("ActiveTrade", "Active trade to apply on", "", "");
strategy.parameters:setFlag("ActiveTrade", core.FLAG_TRADE);

Now, how can I retrieve the selected trade's ID? I assume it is:

Code: Select all

instance.parameters.ActiveTrade

...right?

Then finally, how can I see if it's a long or short trade? In other words, I need to determine if this trade is "Buy" or "Sell" so that I can reverse it.

Thanks, you guys are the best!

Exactly so.

Then finally, how can I see if it's a long or short trade? In other words, I need to determine if this trade is "Buy" or "Sell" so that I can reverse it.

Code: Select all

-- try to find a row in the list of the trades:
local row = core.host:findTable("trades"):find("TradeID", instance.parameters.ActiveTrade);

if row == nil then
   -- row is not found. closed?
   row = core.host:findTable("closed trades"):find("TradeID", instance.parameters.ActiveTrade);
   if row ~= nil then
      -- closed!
   else
      -- ???: wrong trade id passed!
   end
else
   -- row is found, get direction:
   local dir = row.BS;
   if dir == "B" then
      -- long trade

   else -- dir == "S"
      -- short trade

   end
end

BTW, hint:

Strategies like this usually ought to be stopped when the action is performed (trade is reversed in your case). To do it right from the strategy just use:

core.host:execute("stop");

Nikolay, you are a legend my friend, that was exactly what I was looking for!

Thanks so much!

P.S. Awesome tip about stopping the strategy, because the strategy I'm coding should do exactly that.
