New Pine Script: Spot Martingale Strategy

Pine Script Strategy

This is an improved version of previous Martingale strategy. We have fixed the Stop Loss function to be able to calculate drawdown of cumulative all positions.

Normally we do not use SL for BTC/USD trading, but for Altcoins, we strongly advise to use SL function.

This pine script is actually meant for Strategy Backtester, although you can use it with API bot + tradeadapter. Once you get the best setting, apply it into Binance, Kucoin, or Bitget bot.

Personally, i find Kucoin has the most user friendly bot. However, u can find the best Spot Martingale bots selection in BitGet.

Strategy Description: It places BUY order and double down (according to the multiplier) when the price got lower. TP and SL as per your setting. This strategy works best during bearish period with recovery pattern.

Recommended Setting:

Pair: BTCUSDT (Binance/Kucoin/Bitget)

Time frame:5min

*At the moment, I am using TradingView Premium version, so TF5min will automatically give you backtesting range to 8 weeks back. For Essential version, TF5min will give you range about 4 weeks.

The code as follows:

//@version=5
strategy(“SpotMartingaleBacktester[capayam.com]”, overlay=false, initial_capital=100, default_qty_type=strategy.percent_of_equity, default_qty_value=100, pyramiding=99, commission_type=strategy.commission.percent, commission_value=0.12)
// This backtester is to be used for testing before entering into Kucoin Spot Martingale setting
// In Kucoin setting, it does not include first buy in the max position;
// That means if u put the setting here as max Pos 8, in Kucoin the position is 7 [+1 to include the IB]
// Default setting is 100USDT capital with Multiplier 2x, the IB as follows:
// …Max pos 5, IB 3.23usdt
// …Max pos 6, IB 1.59usdt
// …Max pos 7, IB 0.79usdt
//… Max pos 8, IB 0.37usdt
// Default setting is 100USDT capital with Multiplier 1.5x, the IB as follows:
// …Max pos 5, IB 7.58usdt
// …Max pos 6, IB 4.81usdt
// …Max pos 7, IB 3.11usdt
// …Max pos 8, IB 2.03usdt
