Rules (strategy, entry, exit)

Main rules:

1. EA opens a trade

a. sell, if price touches upperBB //mean-reversal strategy

b. buy, if price touches lowerBB

2. open at the same time a hedge trade (in opposite direction)

3. if trade goes in loss, TP of hedge trade is triggered

4. if trade goes further in loss, trade hits SL

5. but if trade goes back to entry, then enter a new hedge trade (with same entry, TP, SL).

6. if trade goes further in profit, trade hits TP. 


Misc rules:

⦁ EA is fully automated

⦁ all orders are instant orders

⦁ only 1 order is open at a time

⦁ only open an order, if spread<0.5 pips

⦁ only exit an order, if spread<0.5 pips

EA parameters

Trade management

⦁ on/off: EAisAlwaysOn =on (default)

⦁ lotsize: 0.02

⦁ TP_SL_method: [fixed, fixed upperband to centerband, fixed upperband to lowerband, dynamic from upperband to centerband, dynamic from upperband to lowerband]

⦁ TP:

⦁ fixed: [20] pips

⦁ fixed: from upperband to centerband/lowerband //use fixed TP at entry. RR: 1:1

⦁ dynamic: from upperband to centerband/lowerband //use dynamic TP as bands widen. RR: 1:1

⦁ last High/Low, that is minimum [20] pips from entry and max [50] pips

⦁ SL: 

⦁ fixed: [20] pips

⦁ fixed: from upperband to centerband/lowerband //use fixed TP at entry. RR: 1:1

⦁ dynamic: from upperband to centerband/lowerband //use dynamic TP as bands widen. RR: 1:1

⦁ last High/Low, that is minimum [20] pips from entry and max [50] pips && SL<=TP


Hedge trade

⦁ useHedge: on/off

⦁ resetHedgeAfterTP: on/off //on means, if hedge_TP is hit, then set a new hedge trade (with exact same entry, SL and TP) //new hedge trade is pending order //delete pending order, if original trade hits SL. 

⦁ lotsize hedge: 0.01

⦁ hedge_TP_method: [fixed, fixed centerband, dynamic centerband] 

⦁ hedge TP_fixed: [10] pips


Trade direction

⦁ on/off: changeBuytoSell. //this means, buy = sell and sell = buy //momentum strategy

⦁ TradeLong=true

⦁ TradeShort=true

⦁ on/off: if sell order hits SL, then only open buy orders

⦁ on/off: if buy order hits SL, then only open sell orders





Martingale

⦁ useMartingale: on/off //on means, every new trade gets more lotsize until TP is hit

⦁ maxOrders: [9] //this means, after 9 losses, the EA starts from 0.01 lotsize for the next trade.

⦁ lotsizeMethod: [fixed, add, multiply] //add= lotsize + lotsize. //multiply= lotsize x lotsize

⦁ lotsizeStep: [0.03] 

⦁ example:

⦁ //add = order 1: 0.03 lot, order 2: 0.06, order 3: 0.09 lot

⦁ //multiply = order 1: 0.03 lot, order 2: 0.09, order 3: 0.27 lot

⦁ resetMethod: [fast, slow] 

⦁ example

⦁ //fast means, if a trade hits TP, then reset lotsize to 0.01 for the next trade.

⦁ //slow means, if a trade hits TP, then decrease lotsize for the next trade. For example, order 1 was 0.03, order 2 was 0.06, order 3 was 0.09. If order 3 hits TP, then the next order decreases lotsize to 0.06 (which is the lotsize of previous trade)
