BreakEven & Trailing Profit: complete function

robertogozzi · Mon, 18 Mar 2019 14:07:37 +0000

The purpose of this code is to: set BreakEven after TRAILSTART profit (in Pips) add a Percentage (BASEPERCENT) to lock in some profits increase that Percentage each STEPSIZE chunk of pips (20% will increase BASEPERCENT by a factor of 0.20, thus, say 30%, would become 36% after the first step, then 43.2 on the second step and so on…) to lock in more profits as they move towards TP make sure the exit price meets the broker’s minimun distance requirements to avoid unpredictable exits IF Not OnMarket THEN // // when NOT OnMarket reset values to default values // TrailStart = 30 //30 Start trailing profits from this point BasePerCent = 0.200 //20.0% Profit percentage to keep when setting BerakEven StepSize = 10 //10 Pip chunks to increase Percentage PerCentInc = 0.100 //10.0% PerCent increment after each StepSize chunk RoundTO = -0.5 //-0.5 rounds always to Lower integer, +0.4 rounds always to Higher integer, 0 defaults PRT behaviour PriceDistance = 7 * pipsize //7 minimun distance from current price y1 = 0 //reset to 0 y2 = 0 //reset to 0 ProfitPerCent = BasePerCent //reset to desired default value ELSIF LongOnMarket AND close > (TradePrice + (y1 * pipsize)) THEN //LONG positions // // compute the value of the Percentage of profits, if any, to lock in for LONG trades // x1 = (close - tradeprice) / pipsize //convert price to pips IF x1 >= TrailStart THEN // go ahead only if N+ pips Diff1 = abs(TrailStart - x1) //difference from current profit and TrailStart Chunks1 = max(0,round((Diff1 / StepSize) + RoundTO)) //number of STEPSIZE chunks ProfitPerCent = BasePerCent + (BasePerCent * (Chunks1 * PerCentInc)) //compute new size of ProfitPerCent ProfitPerCent = max(ProfitPerCent[1],min(100,ProfitPerCent)) //make sure ProfitPerCent doess not exceed 100% y1 = max(x1 * ProfitPerCent, y1) //y1 = % of max profit ENDIF ELSIF ShortOnMarket AND close < (TradePrice - (y2 * pipsize)) THEN //SHORT positions // // compute the value of the Percentage of profits, if any, to lock in for SHORT trades // x2 = (tradeprice - close) / pipsize //convert price to pips IF x2 >= TrailStart THEN // go ahead only if N+ pips Diff2 = abs(TrailStart - x2) //difference from current profit and TrailStart Chunks2 = max(0,round((Diff2 / StepSize) + RoundTO)) //number of STEPSIZE chunks ProfitPerCent = BasePerCent + (BasePerCent * (Chunks2 * PerCentInc)) //compute new size of ProfitPerCent ProfitPerCent = max(ProfitPerCent[1],min(100,ProfitPerCent)) //make sure ProfitPerCent doess not exceed 100% y2 = max(x2 * ProfitPerCent, y2) //y2 = % of max profit ENDIF ENDIF IF y1 THEN //Place pending STOP order when y1 > 0 (LONG positions) SellPrice = Tradeprice + (y1 * pipsize) //convert pips to price // // check the minimun distance between ExitPrice and current price // IF abs(close - SellPrice) > PriceDistance THEN // // place either a LIMIT or STOP pending order according to current price positioning // IF close >= SellPrice THEN SELL AT SellPrice STOP ELSE SELL AT SellPrice LIMIT ENDIF ELSE // //sell AT MARKET when EXITPRICE does not meet the broker's minimun distance from current price // SELL AT Market ENDIF ENDIF IF y2 THEN //Place pending STOP order when y2 > 0 (SHORT positions) ExitPrice = Tradeprice - (y2 * pipsize) //convert pips to price // // check the minimun distance between ExitPrice and current price // IF abs(close - ExitPrice) > PriceDistance THEN // // place either a LIMIT or STOP pending order according to current price positioning // IF close <= ExitPrice THEN EXITSHORT AT ExitPrice STOP ELSE EXITSHORT AT ExitPrice LIMIT ENDIF ELSE // //ExitShort AT MARKET when EXITPRICE does not meet the broker's minimun distance from current price // EXITSHORT AT Market ENDIF ENDIF

Well, not sure I’m happy with this. This thread is titled “breakeven-trailing-profit”. It was exactly this phenomenon of putting Trailing Profits above the price (for Longs) that works like a charm. And now, this phenomenon is killed and this code turns into an ordinary trailing stop. You don’t need the last min(close…) or max(close…) modifications to prevent trailing profits, if that’s what you really want. Just fill in “1” instead of “100” in the next line:

Change 100 into 1

ProfitPerCent = max(ProfitPerCent[1],min(100,ProfitPerCent)) //make sure ProfitPerCent doess not exceed 100%

1

ProfitPerCent = max(ProfitPerCent[1],min(100,ProfitPerCent)) //make sure ProfitPerCent doess not exceed 100%

I guess the limit orders were introduced for a reason. When you eliminate the possibility of Trailing Profits above the price, no need for limit orders anymore. The whole IF … ELSE … ENDIF around stop and limit order can be replaced by one line “SELL AT SellPrice STOP” for longs. That’s what I call an ordinary trailing stop.

Personally I will continue with the extra-ordinary Trailing Profit version. In backtest I have seen 75% of the Limit orders (trailing profit) being granted, only 25% needed the SafetyNet I introduced. Nice bunch of bonusses compared to a trailing stop where you always return a bit to the market. I simplified the part with Steps and Chunks and no longer let BasePercent also influence the increments. Same good results, but simpler and less parameters for the optimiser.
Thanks for your effort.

Sure @SnorreDK. Please find attached the ITF and a little document with a explanatory diagram and some screen captures.
I also deleted the lines that, in the original code, update the stop loss after accumulating new positions. My strategies do not accumulate new positions, so I never studied this part of the original, nor checked its correct working. If you want it back, you know where to get it.
Have a peek in the document, just 3 pages, mainly screen captures, not too much reading.
