buy with stop parameter buys far under the current price

[Hungryarie]

Hi, thanks for making this wonderfull programm!
I've made a strategy and I am playing with the parameters, but when I place a buy order with the stop parameter it will buy far below the actual price.

curent OHLC: O:9664.45, H;9728.13, L;9661.0, C:9717.73

self.buy(stop=8940.3, limit=9717.7, tp=11272.6)
the trade is done with EntryPrice: 8958.19 ExitPrice: 9877.31

You can see in the image that the trade lines are also off.

but when I use
self.buy(sl=8940.3, limit=9717.7, tp=11272.6)
the trade is down with EntryPrice: 9737,155 Exitprice: 9877.33, just as you would expect.

Am I using the stop parameter wrong?

thanks!

This is Backtest(..., commission=) at work, adjusting the entry price.

But why the difference between the two options? (Stop vs stoploss)

Just chipping in - stop price and stop loss are two different things entirely. Recommend reading up on them both.

thanks, so a stop parameter is in fact a pseudo buy parameter at a fixed price.
But how can the algo think is has been bough if the price never reached this stopprice in the example above?

[kernc]

When the stop price is hit, the order becomes either a market order (limit=0) or a stop-limit order (limit != 0).

But how can the algo think is has been bough if the price never reached this stopprice in the example above?

Please see my answer above. 😛
