Conditions on number of trades, reversing trade direction

mrbolt · Tue, 08 Nov 2022 18:43:10 +0000

Good day, all! Hope all are doing well. Kindly ask community help on the coding some backtest example for the strategy. So, long story short: I enter with a buy stop to go long, or a sell stop to go short. I enter with 3 contracts. Position size: 3 contracts, with profit targets of 1R, 2R, and 3R. Once my first target is hit, my stop loss becomes breakeven. If I get stopped out on my first signal, I can stop out and reverse (Go long, get stopped, go short or Go short, get stopped, go long) – only 3 attempts per day. What I did so far: I can track multitimeframe, open and close positions, but can’t realize how to reverse trade if it fails with one direction, how to count correctly number of attempts, in which timeframe? and how to partially close trade. DEFPARAM CumulateOrders = False DEFPARAM PreLoadBars = 0 TIMEFRAME(30 seconds, UPDATEONCLOSE) // No new position is taken after the candlestick that closes 9:45 a.m. FinishTime = 143000 // The market analysis strats at the 30-sec candlestick which closes at 9:00:30 a.m. StartTime = 120000 PositionSize = 3 TickScale = TICKSIZE ScaleReward = 1 PartialCloseCoeff = 3 CloseQuantity = PositionSize/PartialCloseCoeff // Some holidays such as the 24th and 31st of December are excluded IF (Month = 5 AND Day = 1) OR (Month = 12 AND (Day = 24 OR Day = 25 OR Day = 26 OR Day = 30 OR Day = 31)) OR (Month = 1 AND Day = 1) OR (DayOfWeek = 0 OR DayOfWeek = 6) OR (Time < StartTime OR Time >= FinishTime) THEN TradingDay = 0 ELSE TradingDay = 1 ENDIF // We initialize this variable once at the beginning of the trading system. //ONCE StartTradingDay = -1 // We initialize this variable once at the beginning of the trading system.

On 21 Oct at 09:30:31 your code … entered with a Buy (Long) then exit with Sell (Long) then entered with a SellShort (Short) … all these actions occured at 09:30:31.

Then at 09:31:57 y0ur code exit the Short with a Buy / ExitShort at a loss.

Anybody see the scenario on the screenshot above any different to what I state above?? 🙂

what does it mean 1 points for backtesting

We need to allow in our backtests for the ‘broker spread’ else our code / backtest results do not emulate Live trading when the broker makes us pay the spread between buy and sell price.

GraHal, that’s I’m asking, why it happened? I mean I understand closing trade by stop loss or profit taking, but what is that with opening and exiting and opening again in the same bar? stop loss and take profit is much higher then 1 point, that is the question.

Regarding points: sure I understand the spread, I meant, 1 points in Prorealcode settings is how much bips compare to let’s say ES mini contract? I tick is 0.25, so, 1 point is 4 ticks here?

Change your Buy and SellShort to ‘at Market’ orders (remove the ‘at Stop Orders’) and if the zero bars trades stop then you know that the ‘at Stop Orders’ are the cause.

Fault finding is a process of elimination.

What is the difference between Buy Price and Sell Price quoted by your broker for ES Mini?

If ‘ES mini‘ is same as shown on attached, then the spread at 11:16 UK time on 11 Nov 22 is 0.6 points.

Thanks, GraHal, got all your points, really appreciate it.

Have you ever faced with the different results on your trading system when you backtest on Beta version versus previous one? Yesterday I recognized it, maybe because working on seconds time frame data is not stable for backtesting.

Which Beta version (v12?) and which previous one?

At times I have had different results even overnight (then backtest again the next morning) but I put it down to my imagination and move on!? 🙂

So, in PREMIUM V11.1 I got worser results than in BETA V12. I’ll check data, and all other sutff, but this is really weird.

Maybe the backtest engine in beta v12 is ‘kinder’ to your strategy / code and so gives better results?

I would hope such a phenomenon does not exist. 🙂

So, guys. The reason why in Beta results are better than in V11, is because of wrong data, it’s unbelievable, what a mess. So, I checked randomly data on ES futures (minutes timeframe, coz I don’t have another data with Thinkorswim platform), and difference sometimes reaches for 20 points (!!!). So, decided not to use Beta version at all, be cautious here.

It’s the version offered by ProRealTime, so it uses data from IB (as far as I know).
