Calculation of average SL for multitrades

Hi, guys!
Is it possible to create indicator which one will show the level of average Stop loss for multytrades in accordance with risk % indicated by inputs?
I am using indicator like this for getting calculation of an average entry price. (attached)
Below the picture with example.
Blue line is level of Average entry calculated by indicator.
Red line is manually calculated level of Average stop loss.

for clarification:

StopLossLevel =AverageEntryLevel – StopLoss

StopLoss = RiskMoney / PositionSize* TickSize/ UnitCost

RiskMoney = Size * Risk / 100


extern double Risk = 1; // Risk tolerance in percentage points



Size = AccountBalance()

PositionSize= OrderLots()

UnitCost = MarketInfo(Symbol(), MODE_TICKVALUE);


TickSize = MarketInfo(Symbol(), MODE_TICKSIZE);

My request was executed by the ever best coder!

Nice Idea! Applause!

I do average EVERYTHING. Could not find anything better than that approach.

One idea from me. I think it is equally, if not more, important to average the TP per trade.

I hate to be the Debbie Downer, but I'd strongly advise not using any of the methods presented in this thread. There is only one scenario where average price (as it's being calculated) is relevant and those conditions are:

1. All orders have the same exact lot volume
2. All orders are the same direction

Outside of this specific scenario, average price (sum(prices) / #orders) means absolutely nothing, and I'm not sure about you (reader) but if I have multiple orders on the same instrument they're rarely ever the same lot volume.

Consider the following example:

A pc retailer places two orders for pc's from his vendor. The first order is for (1) pc @ $100/ea and his second order is for (100) pc's @ $200/ea. If we were using these "average price" calculations we'd calculate his average price to be $300 / 2 orders. Is this his real avg price? Not by a long shot. We know that in this case we'd need to use volume adjusted averaging so the real net-price is

It doesn't end there... Let's say he sells a pc for $500, what is his net acquisition cost? Obviously the sale wouldn't have any effect on the acquisition cost so his net-cost is still $199, BUT if we use these "average price" calculations we'd end up with $800 / 3 orders for an "average price" of $267, which obviously makes no sense at all...

So the point is that in order to be relevant, one must calculate the volume-adjusted-net-price which requires a sorted pool of orders - then calculate them one-by-one in the order they were placed for an accurate "netting" position.

I have meant as generic approach. It is one's responsibility to calculate things correctly. So, no arguments here. I agree with you completely.

Shortly put, as generic approach only, to average loss and profits seems the best to me...

I assumed you'd know better... it was a general warning to anyone stumbling across this thread
