EA Market Upload - [Invalid Price]

[Tyler James Thomas]

Hello,

I am attempting to upload my EA to the Market place and I keep getting this validation error. I don't really see the issue since my price / sl / tp all appear to be valid. Any help would be much appreciated.

I cannot reproduce in my strategy tester.

Here is validation output:

Thanks for responding Fernando. I have searched the forums extensively and I have read the article and implemented the majority of the checks hence why I posted here. I have yet to find information in that article that would relate to the issue I am experiencing with [Invalid price]. Taking the information provided by the logs (which I cannot reproduce on the exact symbol and timeframe in my Strategy Tester) I see nothing invalid about the price, I have gone as far as adding this simple code to prevent my BuyStop and SellStop from potentially failing:

if (buyStopPrice < SymbolInfoDouble(_Symbol, SYMBOL_ASK)) return;
if (sellStopPrice > SymbolInfoDouble(_Symbol, SYMBOL_BID)) return;

So since I have spent several days troubleshooting I figured I would post here in case someone has experienced the same symptom and am hopeful that if I can find my solution it can be captured here for someone else to use in the future.

You are ignoring the Stops Level and Freeze Level. The following is from the MQL4 documentation but it is still valid for MQL5 ...

Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial

StopLevel Minimum Distance Limitation.

A trade operation will not be performed if any of the following conditions is disrupted.

Order Type	Open Price	StopLoss (SL)	TakeProfit (TP)
Buy	Modification is prohibited	Bid-SL ≥ StopLevel	TP-Bid ≥ StopLevel
Sell	Modification is prohibited	SL-Ask ≥ StopLevel	Ask-TP ≥ StopLevel
BuyLimit	Ask-OpenPrice ≥ StopLevel	OpenPrice-SL ≥ StopLevel	TP-OpenPrice ≥ StopLevel
SellLimit	OpenPrice-Bid ≥ StopLevel	SL-OpenPrice ≥StopLevel	OpenPrice-TP ≥ StopLevel
BuyStop	OpenPrice-Ask ≥ StopLevel	OpenPrice-SL ≥ StopLevel	TP-OpenPrice ≥ StopLevel
SellStop	Bid-OpenPrice ≥ StopLevel	SL-OpenPrice ≥ StopLevel	OpenPrice-TP ≥ StopLevel

FreezeLevel Limitation (Freezing Distance).

Market orders can not be closed if the StopLoss and TakeProfit values violate the FreezLevel parameter requirements.
StopLoss or TakeProfit orders can not be modified if StopLoss or TakeProfit values violate the StopLevel parameter requirements.
Pending orders can not be deleted or modified if the declared open price violates the FreezeLevel parameter requirements.

Order Type	Open Price	StopLoss (SL)	TakeProfit (TP)
Buy	Modification is prohibited	Bid-SL > FreezeLevel	TP-Bid > FreezeLevel
Sell	Modification is prohibited	SL-Ask > FreezeLevel	Ask-TP > FreezeLevel
BuyLimit	Ask-OpenPrice > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
SellLimit	OpenPrice-Bid > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
BuyStop	OpenPrice-Ask > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
SellStop	Bid-OpenPrice > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter

Thank you for pointing me in the right direction Fernando. In case it's helpful to anyone else implementing SYMBOL_TRADE_STOPS_LEVEL overcame my issue.

double stopLevel = SymbolInfoInteger(_Symbol, SYMBOL_TRADE_STOPS_LEVEL) * _Point;
double buyPrice = NormalizeDouble(ask + stopLevel, _Digits);
trade.BuyStop(lotSize, buyPrice, _Symbol, sl, tp, ORDER_TIME_DAY)
